Good quality, clarity, and feel, but required some effort to keep power button from being pressed down by the case.

I just received this case and my initial impression is that it is of good quality construction and should hold up well.  I have no complaints about the clarity of the cover and I like that it came with protective covers on both sides of the clear cover.  The plastic bag that it comes in has a quick scan sticker and text that indicates to scan it for a video detailing installation.  Although the video is for an iPad, the point still gets across and it isn't rocket science to install it.  Once installed, I had problems getting the Kindle screen to stay on. I was able to figure out that the problem was that the case's power button "extension" (for lack of a better word) was slightly too big and was pressing the power button down on it's own.  If I pressed it, I didn't get the "click" feel of pressing the button since it was always slightly depressing it.  I figured there were two possible solutions (short of returning the case) - trim the interior side of the power button extension or add tape to the interior of the case all around the power button to create some stand-off space.  I decided on the latter and added two layers of athletic tape across the interior side of the case with the power button and trimmed around it with an x-acto knife.  Reassembled the case and it works like a charm with no evidence of tape from the outside.  4-stars because of requiring that effort - would be a 5-star product otherwise.  Probably just got unlucky with a unit on the edge of the standard manufacturing tolerances.  I would still consider buying one again.

I've had this case for 4 months now and I'm replacing it with something else soon. My first impression of this case was that it was very high quality. It is a very high quality case but it does have a few problems. First of all, the fact that Samsung has made such a large phone so light weight is a feat in itself. Say goodbye to you're light weight phone of you get this case. The TPU rubber portion of the case is tough as iron. Unfortunately, it weighs almost as much as iron. I was grateful that the case was so tough and protective considering the risk of damaging my investment so I overlooked the added weight. I have had a few significant drops since purchasing this case and the phone came through like it was in a Abrams tank. It is a very protective, well built case. It is also a good looking case that is almost flawlessly designed. In spite of the weight, I probably wouldn't be replacing it, but recently I noticed a small crack above the volume keys. And that is where the greatest weakness of the case is. The PC shell portion of the case has a very thin bridge that wraps around the volume keys. Just above the volume up button a crack developed. I'm not sure if it cracked when I dropped it or if I cracked it while trying to take the phone out of it (which can be quite difficult). Either way the plastic is way too thin at that point. I didn't do anything out of the ordinary to remove the phone from the case. It is simply a very weak spot. A few other issues: the color has begun to wear through on the squared edges of the PC shell and the white PC material is showing through slightly. Also the buttons require much more force to push because of the toughness of the TPU rubber. The headphone jack hole, as well, is not large enough to accommodate all jacks. The shell is also kind of slippery which actually caused me to drop my phone at least once. Anyway I'm looking forward to new lighter weight case with open button access and larger jack hole. Hope this review helps you make an informed decision.

I ordered 3 of these cases in 3 different colors.  The case feels and looks nice and fits the HDX 7 well.  All in all I think it is pretty nice but with a major caveat.  Out of my 3 cases, the power buttons on 2 of them do not properly align with the power button on the device--they are hard to press in and get stuck pressed in, causing the device to randomly turn on and off.  I ended up returning 2 of them and ordering a different case from a different vendor.  The one that fit well is great, but 1 out of 3 cases being good is not great.  Many other cases don't built physical buttons into the case and just leave a big hole through which to press the button, probably for this very reason.

[Update]:  I have adjusted my rating upwards from 3 to 4 stars because of the great customer service in working to resolve this issue.  They were very prompt and helpful with providing replacement cases of a different style that work well.

This case comes with Apple Pencil holder so It will be perfect for those who prefer to carry Apple Pencil with the iPad all the time, but the only problem I am having is the "power button." It needs to be pressed hard to trigger the power button. It's both annoying and frustrating. HOWEVER, other than that, it is quite a solid case with high quality materials and feeling. Highly recommend this product.

The case feels very nice and is high quality construction, but has some drawbacks. It adds more thickness to the phone than I would like, and also the magnetic clasp doesn't really work when you have 3 credit cards in the cover.  Contrary to one reviewer, I can use the phone without exposing my cards - just fold the kickstand back on itself, and you can hold it with the cards against the phone.  I'll probably be keeping the case because it looks and feels so nice - but it's not perfect.

Very nice case - great construction, great feel, study.  Case went on well and appears to provide good protection for very short drops and bumps.  I ended up cutting the little flap that covers the power as it was too annoying to move it manually whenever I wanted to top the phone's power off.  Redirects audio to the front of phone - very useful.  Was able to use a metal plate (in conjunction with magnetic mount) between layers of this case with no issue.

Great feel, doesn't get in the way of any ports/buttons. The only complaint would be removing and putting it back on. It can be a little difficult and I get scared that I might bend or break the metal part. Other than that quality case.

The quality is very good.  Appearance is classy.  BUT -- the stiff rubber covers the volume and on/off switch making it difficult to push the buttons. Since the phone goes to sleep mode a lot to save power, it means I hit on/off button A LOT.  I was determined to use it so I cut out the area around the buttons and it works just fine now.  Would have rated it a 5 if not for the dumb design that took time to work around.

Great case! Super high quality. Only gripe is there's no cutout for power and volume buttons and they are really difficult to feel for.

The quality of the case is excellent.  It feels and looks premium, and the front pocket came in handy for holding documents recently while traveling.  The only gripe I have is with the top-front portion that holds the tablet in place.  Whenever I'm using the front camera, it protrudes enough that it actually cuts off a portion of what the camera can capture.  Maybe this area will soften up over time, but it's currently stiff enough that it returns to place after I've moved it out of the way.

I recently purchased this case for myself and for my mother, and I am truly pleased with the product. It's sleek but hardy, and does everything I need it to do. It's good quality and a great value, and I'm really glad I found it! My mother's case functions perfectly and she loves it. However, my case seems to be defective, as it constantly depresses the power button, often causing my kindle to be unresponsive or to refuse to turn on.  I feel like a jerk, but that's the reason for my low review. But it's a really good case otherwise!

Good case with a great feel in the hand. I love the raised power and volume buttons. This is a big plus over other cases and makes it easy to find the right button. Screen protector is good, but make sure you take your time putting it on.

Good quality and slim. The only issue I have is the volume buttons are harder to press than I'd like. I don't know if the case didn't get made so it was lined up right or what. The power button is fine.

The case seems like good quality, but cutouts are missing for power. That's a pretty big thing to miss. Other than having to trim my own hole for the power port, it seems like a good quality case that will last a long time.

PROS:

This case has a wonderful matte finish both inside and out.

The case has a snug fit, yet is very easy to install and remove.

The port cut-outs are generous. I have had problems with other cases preventing cables from being plugged into the headphone jack, but this case has had no problems allowing for those same cables.

The volume rocket and power button are not difficult to press. They do change the feel of the button presses (obviously), and do make it slightly more difficult to press the buttons, but if your phone's buttons are slightly loose in their sockets like mine are, the solid feel is actually quite nice. I use the buttons to change volume while running or to switch tracks while listening to music (I rooted my device), and I have zero complaints about the buttons becoming difficult to use with this case.

The buttons are also easy to quickly locate, despite not protruding far from the case.

CONS:

The black of the case is different from the black of the Nexus 5 body, but this slight difference is only apparent when looking closely in certain lighting conditions (the Nexus 5 body is visible through the camera cut-out).

The camera cut-out is not aligned precisely, so that the camera is off-center in the cutout. It's not so bad that one would notice just by glancing at the phone, but it is apparent when one makes it a point to examine the case.

OTHER:

Others have complained about the injection point being annoying (if, for instance, they use their pinky to support the phone by placing it at the center of the bottom of the phone). However, a comment by Diztronic in response to these complaints indicates that they have changed the injection point, and my case (ordered in July 20) does indeed have the injection point moved to the bottom right corner, to the right of the "speaker" grill" (this is actually the microphone location). It's out of the way and doesn't bother me (I, too, use my pinky to support the phone).

As a matter of personal taste, I would prefer that the rim around the front of the case also have a matte finish. I think the shiny TPU looks cheap.

One user complained of the ends of the case flaring out. I have not had this problem, and it appears other reviewers have not experienced this, either.

For those not familiar with TPU cases, they are easily bendable, but don't compress as much (and thus do not provide as much shock absorption) as a typical two-piece case would provide (such as a Case-Mate Tough or Speck CandyShell). Those cases are more of a rubber one could squeeze a bit between one's fingers. TPU, again, doesn't really compress. So while this case will provide some protection from drops, it won't provide as much as a bulkier case. I would trust this case to protect the phone from a pocket-height drop, even on the corner.

Overall, 10 dollars for an attractive matte black case isn't a bad deal. It doesn't add much to the size of the device (still feels small in the hand), it protects from scratches, and it allows me to set the phone down on hard surfaces without worrying about having to be gentle with it. Since the port cut-outs are sized well, it doesn't make the device anymore difficult to use than when it's naked.

Lastly, it's great that a company responds to user complaints on here and *actually changes the product to make customers happier*.

I've no regrets with this case (besides wishing I could keep my sexy Nexus 5 naked without worrying about it).

Seems a bit difficult to use the side buttons (volume control) and wish the bumper wasn't white but it is a sturdy case of good quality if you don't want to spend a lot of money.  I am pleased.

I agree with some of the other reviewers that it seems like the placement of power button doesn't feel like you are actually pressing and making contact with the device all of the time. I think it will just take a little bit of getting used to it. Other than that, the phone fit into the cases perfectly, I didn't struggle at all with fitting my phone into the case.
