I recently received my black Devilcase aluminium bumper case today in the mail off Amazon and took some pictures. I haven't had it nearly long enough to comment on its performance, but I'd say so far that it's pretty damn good. I've taken pictures of the bumper on my black HTC One and my friend's silver One as well.
Below is the packaging. Came with the bumpers screwed together with two screws, a small screwdriver and a spare screw. The spare screw was a nice thought as I almost immediately lost one of the screws on my carpeted floor. The bumpers are definitely not going to fall apart, though since it covers the SIM slot, if you're ever out and you need to get the SIM out, you're out of luck unless you plan on carrying very small screwdrivers and a paperclip to eject the SIM slot.

Bumpers: Both bumpers are lined with a soft rubbery material. The volume rocker cover is actually quite nice and I think it makes it easier to adjust the volume with the bumpers than when the phone was naked since the rocker is raised. There is a gap between the power button and headphone jack since the back is rounded, which I've included below.
After installation: The bumpers are slightly higher on the corners, which I feel improves your grip on the One. My black One also has a fullbody Skinomi protector, though I cut off the sides on the back protector
Volume rocker:
On the silver One:
Gap: There is a gap on the power button and headphone jack since the One has a curved back. Not a big deal at all since the bumpers have to be straight. Is also a good indicator of how much space is placed between the phone and the edge of the bumper if you were to place it flat against a surface.
As for the back of the phone... I would recommend a protector on the back. The bumper raises the phone slightly off a table surface, but if you were to slide the phone around or if there was any dirt or grit on the table, I'm not the bumper would keep the phone away from that... I suppose it's a personal choice, but I like the extra peace of mind. In regards to the front of the phone, you can clearly see the bumper around it, but again, I would recommend a screen protector. I found Skinomi's full body protector to be affordable ($15 on amazon) and easy to install (would also recommend cutting off the edges on the back that are supposed to fold over onto the sides with scissors or x-acto knife and ruler before installing... the edges really don't stick very well and you won't need them if you're using the Devilcase).
The gaps on the power button and headphone jack don't bother me and I think it even helps me find the power button since it's so flat. I forgot to include a picture, but there is a hole for the microphone, so the bumper does not cover it.
In conclusion, I'm so far very satisfied with the Devilcase. I think it's a great case and would go very well with a back and front screen protector. To be fair, I have no idea how well it'd hold up compared to a beast of a case like an OtterBox, but I believe the OtterBox is probably considerably larger (and not as good-looking) as the Devilcase and I think that's just comparing apples and oranges... both are different types of cases and fulfill different needs. For myself, I'm just looking for a case that won't substantially increase the size of the One and can still over some to good protection against minor drops and scratches and slim cases like the Nillkin are what I usually gravitate to, but the Nillkin does not cover ALL sides of the One, such as the top, bottom and volume rocker, and dirt can get in-between the case and phone. Personally, I think the Devilcase is sturdy, great looking, improves my grip on the phone as well as the buttons, so I'd call this a keeper
Did you have a chance to test the signal? Can you let us know where you live? Big city or small town?
Thanks for the great detail review. It's very useful. I'm gonna get one :good:

I haven't done a signal test like checking the signal strength before and after the bumper, but I'm honestly not worried about it. A bumper like this would not affect the signal given how HTC designed the One. I have used the phone while out and can say that I did not experience any signal loss where I should have had service.

I just got the case in silver and the case is effecting my signal for LTE. I'm on AT&T and in my house i get 2-3 bars of LTE, the second I put on the case I lose LTE completely. When i take off the case the LTE comes back on. I still do get 3-4 bars of HSPA with the case on so it looks like its just effecting the LTE for AT&T though

Any/all aluminum case/bumper will affect signal unless it is designed like ElementCase's with plastic inserts to disrupt it. It creates almost a mini field, which disrupts signal.
From a screenshot I saw before, the devilcase doesn't seem like it's the worst, although like above, it can become very noticeable if signal isn't the strongest already. 2-3 bars LTE going to 0 LTE is a pretty big deal

I suppose, but the antenna is also on the back of the phone as well. If it does affect signal, I doubt it would affect it very dramatically. I can't comment on personal anecdotes of other members, though, unless you checked the signal in the same exact spot and put the bumper on and off several times... it should be repeatable. But again, these are just my views.

Yea, but the aluminum bumper will create basically a force field and if you know about force fields, it's essentially how should I say like in the shape of a sphere around the device.
The One design works in general because all the injected plastic keeps the aluminum body from touching each other and creating this field. The antennas are housed in it so there's no issues. Just like how the iPhone's since the 4 have had the antenna bands completely disconnecting the aluminum band around the phone. But if you connect these bands creating the antennagate problem you get the signal problems, which is like putting an all aluminum bumper around your phone (It just might not be as bad in this case)
All in all though, everyones experience will differ since no one will have the same scenario. Signal degradation will be far more noticeable to certain people, while barely noticeable to others. It's a toss up, but in general if signal in your area already isn't that great like around 3 bars. An aluminum bumper like this will make a bigger difference.

It seems like with the bumper on it is only effecting the LTE. I really wanted to keep the case so I tested it over 10 times in my home office. I basically sat in the same spot, had the phone naked and I would have 2 bars of LTE, once I put the case on, within 30 sec to a minute, the LTE would disappear and I would have 3 bars of HSPA. The signal works fine and I have no problem making phone calls and stuff but since I do a lot of web browsing and use the tethering option, the loss of LTE with the case is a big deal for me. For someone that doesn't need the LTE, i wouldn't imagine this would be a problem. once again, this is only for AT&T.
If anyone else has AT&T and has the case, can they tell me if they have the problem also?
Thanks.

It's just because signal isn't the strongest in your area. It's affecting all signal, not just LTE. LTE just isn't as strong of a signal compared to HSPA etc...It's like going from HSPA to EDGE when your signal gets weak. Anyone else with a similar situation will experience the same problem. This is not a new issue, aluminum bumpers started with the iPhone 4 (I assume since that's the first I played around with them and saw them more widespread on the internet). The kinks have been ironed out though with ElementCase at least though. I'm surprised no other brand has really followed in it's design choice to really fix the signal degradation problem.

I'm on AT&T, but through Straight Talk, so I don't get 4G or LTE. I did check signal strength before and after the bumper install, but there was virtually little to not change, so I'm afraid I couldn't say why you're losing LTE signal.
Video
I took a video so you guys can see what I am talking about but I wasn't able to upload it since i don't have 10 posts I can't post the link to youtube. If anyone wants to help me out upload the video or tell me how I can attach a link or do the youtube on here I can show you guys what i'm talking about.
On the video you can see it go from 2 bars on 4G LTE then when I put on the case it completely drops LTE and goes to 1 bar on HSPA. I'm not knocking the case in anyway. I would love to keep the case but there is definitely a interference for me on this case. Everyone though will be different but I thought I would share my experience (once again this is ONLY on AT&T).
Thanks

I never heard of this force field theory...
If you mean electromagnetic fields that DO disrupt radio signals because they interfere... I dont see how a piece of aluminum surrounding the phone can have an EM field?
Like someone else said, the antennas on this phone are on the back (those white lines). I remember seeing it described that way in a design video as well...
Not sure how much affect there would be from blocking the side plastic.
I really doubt that should make a big difference though, cause guess what, if blocking the sides causes an issue, then thats the whole iPhone death grip fiasco again..
Anyway, I'll wait for more reviews before I buy this bumper as well. It looks great, thanks OP for the pics.
I want the silver, but it seems like only Blue is left in stock, ohw ell.

I asked a friend about the signal issue and he suggested placing insulation in between the phone and bumpers. There's already that soft rubbery material I had mentioned in my original post (which is probably exactly for this issue) that should have been enough to compensate for the signal, but perhaps yours does not have enough? The material is pretty thin, but all it needs to do is keep both antennas from maintaining contact from each other with the bumper. I'd suggest checking to see if maybe your bumpers don't have them.

It's not a force field theory... It's a Faraday box or cage... interesting stuff. If you want to understand how it works, link below!

And, if you don't feel like reading... Wal-Mart is pretty much a big Faraday Box!

miamibest, take cassull's advice and check your padding, eliminate any and all metal to metal contact (even speaker grills) and see if that helps.

My mistake.
Took a quick read, interesting.
But from what I get, the conductive material used as a shield/cage has to either be charged or grounded? And this case would be neither.
Again, correct me if I'm wrong. Because if its that easy to create a Faraday cage, then doesnt the aluminum of the phone itself already create the cage, as that is much more aluminum than the bumper itself.

The aluminum already has charged particles on it before any external source touches it. And when the conductive material gets charged from an external object, the positive and negative charged particles in the material disperse to opposite sides of the surface, particles with the opposite charge of the source being attracted. Since they are on opposite sides, this creates opposing electric fields, negating the charge on the inside of the shell.
Code:
External + Net -
Source (-) + Elect. -
+ Charge=0 -
So when the EM waves (radio waves) get to the phone this phenomena happens.
Depends on the cage's construction. Mesh holes, and conductivity of the material affect the cage's effectiveness, and can be tweaked depending on what frequency/wavelength you want to penetrate. to In the One's case, it's designed for signals to get in via those white strips on the back.

Lmao, I think I get what you're trying to say though. Interesting stuff. Would have to do more reading to understand it.
But anyway, so far from reading the reviews on iPhone version as well, results seem hit and miss? Hm.
I can confirm the signal gets weaker w/ the case on. It's fine at places with strong signal, but at my house with only 1 bar on LTE (ATT), the phone drops LTE n go to HSPA with the case. I have kinda a workaround where i put a tiny spacer (rolled up scotch tape) on the bottom of the phone to create a tiny gap, and the LTE stopped dropping.
I bought a metal bumper off ebay for my Galaxy S3, it consists of a front and a back that screw together, I really like this because it lets the phone breath while still protecting the edges from drops and being metal it's not going to wear out, another nice feature is with these tiny allen keys a thief wont be able to get into your phone quickly and remove the battery/sim/sd card so you might just get a little longer to find your phone :good:

They are nice cases, but I got rid of mine because I had issues with reception when using the case. If you have a strong signal, the case did not seem to affect the reception. However, in my house (my kitchen, specifically) I do not have a very strong signal at all. As a result, I was getting very crappy reception with the phone, especially if I was talking and walked into the kitchen. When I removed the case, the issue went away.
I only had this issue in my house. Just about everywhere else locally, the Verizon signal is pretty good, so no apparent effect of the case.
I wish I had a stronger signal in my house, as I really like the aluminum bumper case...

With this bumper I dropped from -83 db to -95 db. I would hover around high 3 to low 4 bars at work on LTE and this dropped it to a solid 2 bars. I live in a basement at home an only get one bar normally so I had to take it off to pick up any reception. If you are in a good coverage area it shouldn't be an issue, but there is significant signal drop.

Thanks for the feedback, considering it's only a bumper and doesn't cover the back it still blocks signals that's certainly a no go.
The one I have doesn't drop signal. I have a black one and a red one. Got mine from a company in California.

I recently received my black bumper case and it destroys my signal. In some places that I had 4 bars and strong reception I went to no reception. I noticed my phone continuously cycling through reception.
When I get home this evening I will upload the screen shots from the locations to show the difference in signal strength.
Hi, a note to Huawei P8 lite owners, who are looking for nice bumper case - i have bought Luphie Aluminum Metal bumper case (http://www.aliexpress.com/item/Luph...al-bumper-Top-quality-luxury/32363622714.html). Generally it's nice looking metal frame around phone edge.
However - GPS signal is 2 times lower with the frame, maybe you will not notice it in open air, but in the forest (even with few trees) GPS does not catch signal at all. Unfortunately GPS is too important feature for me, so i'm not using this case anymore.
Exactly the same happened to me.
thank you, was thinking about buying it but now i will save my money
and only GPS problems or Network Signal problems too ?
Any chance on having this bumper case here in the Philippines? It's too cool!
Network signal was ok, at least i did not notice LTE/3G issue
weak GPS signal
same problem to me
Got same problem, poor GPS reception, frame removed though it was nice.
GPS is fast and good signal with me but some times it tells me that I am in different location !
Wish I had seen this before I bought one! Didnt notice much difference with the phone signal but the GPS was unusable for use in the car.
Asked ebay seller for my money back! will wait and see what happens!
Why should he return you money ? Only when you return him case, then it make sense...
Case has been returned. If you bought a wheel for your car and it didn't turn making the car unusable wouldn't you also want your money back
phone is still perfectly usable with case. And why should somebody pay for YOUR mistake ? (this thread is here from 28th September 2015, which is now almost 9 months). you should be ashamed...
It's actually normal that you lose some signal. a case made out of conducting material works as a Faraday cage. it's the same principle as wrapping your phone in aluminium foil

You always can expect a small impact in signal reception but in this case the GPS becames absolutely useless in car or when you walk in the street between even small buildings. GSM signal is also affected so if you are in a low signal area you render the full device useless when using this case. I think the sellers should add some notice. I feel cheated.
I wish I had known this post!

Hi!
Aluminium bumper case are very preatty but... will block wifi, raio, GPS signals!!!!!
Aluminium is used as shield in some situations or to reflect signal like wifi booster.
