Protects the phone well as I've dropped it a few times without problems. Only a couple of complaints:  1) Case is pretty slick. I was after a rubbery texture so that the phone would not slip out of my hands. This is smooth and I have dropped the phone due to the finish. 2) The cut outs on the bottom for the head phone and plug are sharp. When typing these cut outs are right on your fingers and it is not so comfortable.

After using a thinner case that did little to protect my Nexus 4, I opted for the well rated KaysCase.  The phone fits snuggly with little chance of it popping out during an impact.  It's highly textured design makes for a sure grip.  The kickstand seems sturdy enough.  The two part case adds a bit of extra protection to the corners.  The first part of the case actually encases the phone and has ribbed sides.  The second part snaps on via the four corners and two side prongs.  The second part has a very textured back and includes the kickstand. And for the more fashion conscious, you could order more multiple cases in different colors to make a two-tone case.

Couple of points to look out for.  The added thickness makes for a more tenuous placement in my car phone cradle.  The cradle now barely is able to grip the sides and a good jolt from a pothole will likely dislodge the phone.  Trade off for the added protection.  The cutouts for the micro USB and headphone jacks may be a little tight if you are using a charger or headphones that have beefier moldings around the plug ends.  And rather than having cutouts for the power and volume buttons, this product encases these controls and you have to press a little harder to operate the functions.  I probably would have oriented the kickstand the other way so that the volume controls were on top rather than the power button. None of these are really complaints but just wanted to point out for others.

I'm particular about my phone cases and I like to have something that gives it protection against minor drops, but doesn't take away the notes slim profile. This case delivers on that. However, I've encountered two drawbacks. One of which is minor and that's the cut out for the power button and volume rocker. I naturally put my finger on the edge of the device when I press those buttons apparently as I've noticed its slightly more difficult to get to the buttons without looking at it. I've been using the case for over a week and have adjusted, but it still feels unnatural. The second part of this case that is most displeasing is that the case is a magnet for the oils on your fingertips. I assure you I keep clean hands. Even washed hands, thoroughly dried and cleaned the case. Yet, after a few minutes of touching the case, it starts to become a fingerprint magnet and gets to feeling particularly greasy and gross. Sadly this isn't the first Spigen case I've had an issue with which is a shame as they are beautiful cases and unique, but this is another one that's a no for me.

Pros: protects phone well, raised lip around the edges of the screen, very affordable, super slim
Cons: finger print magnet, gets dirty easily, and access to the power button and volume rocker are slightly restricted

This case is pretty good but does have a few issues one should be aware of.  I purchased this case recently so only have brief experience with it - no long term experience as to how it holds up over time.

Pro's
- The look of this case is VERY cool and sleek.  I love the frosted plastic with the orange. Also you can see the apple logo under the plastic (which I think is nice).
-  It's nice and thin - so your iphone won't feel bulky.

Cons
- The feel of the plastic is quite slippery in my hand (I feel like I'm more likely to drop it).  I'm more accustomed to heavy duty gel cases (tech 21) however, so it could just be me.
- The plastic is very very hard - It certainly would provide protection for your phone, but it seems that it wouldn't provide much as far as shock absorption.
- As other's have said - YES It is VERY hard to get the case off (I don't have much problem getting it on - but I hurt my finger trying to take it off (I still can't get the darn thing off).
- At the bottom of the phone (where you plug in the charger) the band that wraps around the front of the case seems quite flimsy (there is a 2 inch band of it on the bottom that easily moves -  I could easily see it getting caught on something and easily stretched or broken.  If anyone is confused about this - let me know and i can send a picture.

On first impressions it is pretty impressive. This is my first TPU case, but it seems better than the silicone glossy case I got at launch from Verizon. It is not as grippy as an Otterbox Defender case, but certainly more grip than an Otterbox Commuter series (worst case I've tried) and a naked Razr. And it feels a little more grippy than the Verizon silicone case. Plus this TPU case is incredibly slim and light. And, might I add, this is my favorite looking of all the cases I've tried so far.

The one thing I did notice that differentiates this from the other TPU cases that I've ordered is that the CruiserLite case has holes that are meticulously cut out to allow access to all the buttons, camera, lens, and microphones.  A few other TPU cases on the market cover over the bottom microphone on the back of the Razr, but not this case.  Also, this case covers over the SIM card and MicroSD door cover, which I like.  Very rarely will I need to access my SIM card and I prefer that this be covered over by a case.

This case meets my needs. It is a thick material that fits snug over my phone. My only criticism is that the material is more slick and not easy to grip onto. The product is a overall a good quality for the value I paid. Also, my phone has already survived a fall from my bike at top speed with this case on.

Very nice case. Protects just enough. But it's very smooth and slippery. And gets dirty pretty easily. I would go with something made with rubber grip next time.

The Good : Case is solid & should protect pretty well. The rubber is pretty snug against the phone unlike most cheap cases.

The Bad : The button take 2x the pressure to push in now, But that may be a good thing for the power button. The back of the case is Super smooth & slippery which can make hard to hold on to, Also the M logo indent is not cut out of the back where you would typically place your finger . I ended up using a dremel tool to make the camera hole longer to expose the rubber for eaiser grip. I also roughed the whole plastic back up with heavy grit sand paper as well..

The texture of this case is grainy I suppose was so that it wouldn't be too slippery so it works pretty well except for the fact that the white color picks up dirt VERY easily due to its grainy texture. The phone got black on the sides where my hands were almost instantly and after 2 weeks its already looking old even when I try to use damp towel to clean it a few times a day at the office. I dropped it twice on the carpet of my office and the left corner had a tear in it, I suspect it is because unlike all the other sides, the upper left corner has two openings next to it (one for the volume button and the other for the headphone jack on top) so the piece stands out with very little support. To keep it clean I have to use a toothbrush on soap because the damp towerl doesn't really help...All in all, i think it would be perfect if it was black and that all the openings on the iphone can be wrapped around with the case instead of a long cut to open it both at the bottom, the top, and the side. But to Zero Chroma's defense, I think they came up with a new version that does that and the features that are the highlight of this case works PERFECT when I watch movies on the plane or while travelling....

The case fits well and looks nice but it is rather hard and slick. I fumbled the phone a few times with the case on. Going to switch to another case that has more grips. It's a really good deal for $10 from Amazon ($12 today) but I don't want a case that increases my chances of dropping the phone. If it was softer and not slick, it would have been a keeper. Going to try the Otterbox Celestial next.

This is a good case. It's fairly hard and fits well on the phone. I can push the volume buttons and the power button with ease. It also doesn't block the head phone jack or the lighting power cord slot at all. I think it would protect my phone well if it were to take a fall. The only problem I have with this case is that it doesn't have very good grip. The phone itself is very slick and the case does make it a little less slick by having a matte finish, but I was looking for something with more of a silicone or rubber tackiness to it.

The comments in the question area seem to suggest that it does have a good grip and tacky feel but that is not how the case I received is at all. I wanted something that would hold on to my clothes when it's in my pocket, so it won't slip out and I'm not sure this case is going to work for that. I had a cheap stretchy silicone case for my phone before this and it had much better hand feel but the case was so stretchy, it would fall off my phone easily. I was trying to replace that case with this one because I wanted one that was more rigid. This case has everything I want except the rubberized tackiness on the outside.

If you don't care about the tacky grip feeling, then this is a great case for you.

When I first got the case it had a strange texture when touching it.  Kind of like rubber band texture.  I rinsed it with water but the feeling was still there.  I've used it for a week and texture is still slightly there, but it doesn't feel bad.  It doesn't feel like it will slip out of my hand. On the top and bottom the of case where the material curves up to the screen at the chamfer has a sharp feel to it.  Its still a really nice case.  It doesn't add much weight and its still slim when I put it in my pocket.  The color looks more brown than what the picture Spigen used.

The case is slippery.  Wish it was a matte finish so I could have better grip.  The case is bulky, but is to be expected since it is a battery backup.  I did not leave my phone in the case all of the time because of the bulk.  the case broke because of constant removal of phone.  They could find a better way to open and close the case so it does not break.

The battery back up was awesome and gave me roughly 4-6 more hours of use.

I am pretty happy so far, the biggest plus for me is that all buttons work great -my last case had me hating the phone because it would keep buttons depressed, now I just hate sprint and their lack of 4g let.

Ok back on topic...minor complaints include the soft rubber on the front tends to cling lint to it especially if you are cleaning screen with paper towell. My big little complaint is that there is no soft rubber on back of the case which I find amazing given the fact that it is called commuter so that whatever surface the phone is one it now becomes like a slippery puck due to the slick plastic back. back. This almost caused me to send it back and still has me pondering it's return but I found a spot for the phone in the car so it doesn't slip as much. Also I could not get the screen guard to go on without bubbling and then even worse the sticker they had on it wouldn't come off so even if I had gotten it on it would have left adhesive residue which even with goo gone scratched it to get off.

First time I put it in my car where my old case would be the phone slid off the center console and right under the  car seat. I am keeping it because it really is a slick case that keeps the sleek lines if the phone.

I like the rubber part of this case but it, and the shell, are slippery.  I can see if your hands are even a little damp, the phone might slip out on to the ground.  I thought the materials would be "grippy".  Also, a design flaw is that the micro-usb to lightning connector adapter cannot be inserted into the phone with this case on.  I had to do a little surgery to remove 1 speaker opening on both sides of the lightning connector hole.  Even still, the piece of the case right beneath the phone button still bulges out when the connector is plugged in.  I'm not sure how this got past their QA department.  Overall, excellent build quality & fit and finish are great. Even the case it comes in is excellent; however, I can't say that I really recommend this product due the slippery-ness issue and the connector issue.

It will probably do fine to protect my phone from bumps, but the texture is actually more slippery than the phone itself. I had a TPU case for a different phone and was kind of expecting to get the same grippiness, so I'm disappointed. The colored part is a separate piece that snaps onto the back of the case. I think this part might be some other kind of plastic which is harder and smoother than the rest of the case.

Edit: The seller contacted me and wanted me to be a satisfied customer. We have resolved the issue. The case is otherwise a good case but I would rather have something that is grippy.

Not silicone or rubbery texture, so it slides out of my grip.

Also, oddly the phone now keeps trying to facetime/face dial during calls, which cuts off phone calls. This could be completely unrelated to the case shape or ridge thickness, but worth pointing out. In addition, I've had some complaints about the volume being muffled or too low when using this case. Again, could be unrelated.

My main issue was that this case is NOT grippy.
