Doesn't make iPhone bulky.

It is sleek and smooth to touch. I like it for the decreased radiation. Best price on Amazon.

It's okay, but it doesn't stick to the part of the back of the iPhone. Didn't bother me, as I was just using it under a case.

It's not heavy duty, but it is functional. And it's gorgeous. And slim, so the phone doesn't feel bulky.

I've had it for two days and like how it doesn't make the phone real bulky. Slim enough to slip into my pocket.

Installed easily on my iPhone 7 Plus.  Pushed one small air pocket off to side with provided card.  It's smooth, unobtrusive, and does not seem to interfere with the touch functions. I don't know the protection quality yet, since I haven't dropped it (thank goodness), but it's nice to know it's there.  The screen protector does not go to the edge of my curved screen, which is why I picked it.  I tried two different cases and they fit well without it getting in the way.

Recently got the Iphone 6+ and cases were hard to find.  The Iphone looks very nice and did not want to loose its appearance of a case.  Not sure how well the phone will be protected if dropped so I purchased a clear cover for the front of the phone as well.

Good grip for a simple case that does not hide the iPhone design. No problems with control or port access. Not a case for those looking for drop protection.

It is not super sturdy, but it give adequate protection to my iPhone and is very cheap.  It doesn't add bulk to the phone so it fits nicely in my pocket.

I love the Elago slim cases for the iPhone 4 but I've seen too many people with partially cracked iPhones with them on. I decided to get some solid protection for my iPhone 4 that wasn't Otterbox ugly, if you know what I mean. This case is fine. I wish more reviewers would mention that it's technically a soft case with a hard surface, if that makes sense. I can stretch/pull it on and off whenever I need to wipe dust off my iPhone. It's not the wonderful clear and hard, snap on case that I randomly found at a mall kiosk, but it's been doing what it's supposed to do.

It's cheap, but doesn't look like it.  Not a complicated object so there isn't much extra to say.  It holds my iPhone on the nightstand and looks nice.

I really like the fact that this Otterbox is not huge and bulky (I stopped getting Otterboxes after my iphone 3?--years ago). This one is a pretty aqua, and actually has a pattern on it. My Mophie did not, unfortunately, protect my iphone 6s plus from damage, when I dropped it while getting out of my car. The mophie itself was chipped, and my iphone has cracks on the glass and chips. I don't generally give reviews, but I got this fast, and in great condition.

I just bought this case yesterday and so far I'm pleased. For some time, I didn't buy a case for my iPhone because I thought it would just make it bulkier and not as easy to slide in my pocket.  Yes, the naked iPhone looks better but I don't think the black (yeah, it is really more of a dark brown) Targus Slide case detracts that much from the appearance of the phone.  It is a completely functional case that protects the phone without adding much bulk.  I think the iPhone 5 is very durable.  Once while running in the rain, I dropped my phone and then inadvertently punted it across the parking lot.  The phone survived with only nicks on the metal rim, one of which makes it a bit more difficult to insert the headphone jack.  So the bottom line is that I think added protection that the case provides is worth the down grade in appearance, especially considering there is no functionality loss.  And the price is better than most other cases.  If I again punt this phone across the parking lot, I can replace the case without incurring much expense.  I think that they could have improved the appearance of the case by using black trim and black push button covers  instead of white and by making the case black instead of dark brown, but overall, I'm pleased.

I do not like having bulky cases.  They take away from the look of the phone and add too much weight/size.  This case is thin, adds no weight to the phone and makes the phone look good.  I like that there is a cutout for the apple logo and a slight lip on the front edges.  I used the same case on my iPhone 4 and it was great.  This one is even better, because of the added lip.  It's also nice that they send a logo protection film.

Obviously, this case is not for everyone.  I never drop my phone and take great care of it.  If you are a clumsy person, then you probably need a brick case.

This is really nice...not bulky and most importantly, keeps the phone from slipping and sliding and iPhones have a tendency to do, when not in a case.  It doesn't slip around, but it will still slide into your jeans pockets without struggle.

I don't like having a case on my phone, especially one as good-looking as the new iphone.  But I'm clumsy and phones are expensive, so I went looking for something that would protect my phone without detracting too much from its design.  I ended up with the Spigen Slim Armor case, and couldn't be happier with my purchase.  The metal slate color matches the black iphone almost perfectly - from a distance it doesn't look like there's a case on it at all.

More importantly though, the case fits incredibly well and seems very protective without adding too much bulk (I haven't dropped it yet - I'll update when I do).  It's not quite as thin as many other "slim" style cases, but is definitely smaller than an otterbox or speck case.  I actually like the little bit of added weight and more substantial feel of my phone with this case on it.  The TPU material feels great and isn't as sticky as the silicone liners, so lint and dust doesn't stick at all and it slides in and out of pockets very well.

I also really like that the case doesn't overlap over the glass at all.  It sort of clips to the outer edge of the phone and leaves the whole screen visible.  This also means that almost any screen protector should fit with the case on, but I should mention that the case doesn't come up very high above the screen.  It's nice because it doesn't block my finger from pressing the buttons on the far edge of the screen, but it might not prevent a thicker screen protector from touching surfaces when laid face down.  I'm not bothered by it, but if you want a lot of room between a surface and your screen, this might not be the case for you.

The buttons are super responsive and feel great, and the speaker holes don't affect the sound at all.  The headphone and charger ports are on the smaller side, so if you have  headphones with a huge jack or a fat third-party carger, they may not fit.  Note: my Belkin car charger and Monster iCarPlay cassette adapter (yeah, that's how I roll) fit just fine.

Overall, I can't believe the quality and price-point of this case.  For less than $20, you get a very attractive, custom-fit case that offers decent protection without detracting too much from the slim feel of your phone.  I'd give it ten stars if I could!

I like the way if feels to the touch.  It doesn't feel tacky and I notice how it doesn't even look like there is a protector on my Iphone.

This case has been working for me just fine. I had been hoping to get an otterbox for this phone but they didn't have any for this phone when I was looking. This is definitely no otterbox as far as protection goes but neither is it as bulky or in the way. It looks nice, I can still fit it in my pocket, and it doesn't get in the way of me plugging in my headphones or charger cord. I have of course dropped my phone several times and so far the case has done its job.
