Perfect case except plastic turns yellow over time

This is the best iPhone case on the market in my opinion. I only give 4 stars because the plastic yellows over time, and you must replace to keep it looking perfectly clear (see picture).

Great case, but it's only weakness is that if you play with this change or change it out frequently, the hard plastic will snap in half over time :/

I absolutely love this case. I love that it is completely clear so you can see all of the 5C coloring. It's got rubbery edges but a hard plastic back plus it lifts the iphone screen off the table when sat face down.  The reason I only rated 4 stars is because the clear case is starting to yellow/brown a bit in color. I knew it would do that upon buying it, but I have only had it a little over a month. I thought it would last a lot longer before yellowing.

I bought this case with my new GS3 in November and I still love it four months later.  I have dropped my phone numerous times on concrete (yes, I'm a klutz), and it has saved my phone every time. However, the white color did turn yellow and brown.  I ended up purchasing the black case as a replacement because after only one month in service, my white case looked filthy.  If you have the white GS3, buy the black or one of the other colors.  The white will only lose its color.

This is a solid case... but there is only one flaw. That is that it starts to turn yellow after a while of using it from the dirt and germs being attracted to the case. But it has saved my phone plenty of times! I have dropped it from head height and it protected it like it should have. They just need to upgrade the rubber and it would be great!

I really love this case, it did however yellow over time..but I have a dark blue galaxy so you don't really notice it.

It's a great case, but like all clear cases I've came across this one yellows over time.

There is a protective coating on the case so it doesn't get yellow and mine is already turning yellow. Hasn't even been a month

Updated Review: I bought the Frost one this time around and in exactly 3 months it started to turn yellow-ish again. Pretty horrible. They simply should stop making that color or make it grey.

DO NOT BUY THE CLEAR one. Unfortunately ever other color ill detract from showing the nice M7 metallic finish.

I bought this case for my M7 and it fits well. The openings are good and the buttons are okay too use. The volume rocker does get harder to use. Reason for 3 stars, is that the clear case turned yellowish and brownish in 3 month of in pocket use. It has not been out in the sun or anything. No amount of washing clears it up. I am back to shopping to another case.

Perfect fit for my phone all buttons line up great and the case provides just enough grip when handling the phone.  Downside is that after a few months the case has turned from clear to a yellowish brown color perhaps from the heat of the phone.

I really like this case but I would recommend a differnt color.  The clear one turns an ugly dirty yellow in a short time. I have two of them and they both turned.

I've had the crystal clear case since early July 2015 and it is now yellowish in color. The clear lasted a few months and overall it is a good case.

UPDATE 7/2014: CM4 has had extremely great customer service and it seems like this was some rare phenomena, I'm updating my review to 4 star in lieu of them sending me a new case, and when I receive that, I will give a more in depth review. As mentioned previously, I really still like this case, and it is a GREAT alternative to the Book book style cases out there.

I've enjoyed this case and owned the 4s case in the past as well, BUT this brown case has stained the back of my phone a yellowish brown. It doesn't seem permanent, but it's still very annoying and I now have stopped using it.

Purchased this back in Sept it is now Jan and the case is turning yellow. It is protective and I really liked it in the beginning because my phone looked great but now it looks like a have a gold phone and its white.

I ordered a similar case when I first got my Moto X Pure. It yellowed a bit, but I still liked the case. I wanted to show off the bamboo and metal of this phone, and not have a yellowed case, so I got a new case. This one has softer grippy edges with a much more clear back. It doesn't get hung up either, not too sticky, slides into my pocket easily.

Update:  After a year, this case also yellowed, and the grippy side separated from the clear back. Both plastics yellowed. Good case, but don't expect it to be nice and clear the whole time you own your phone.

Fits my G5 perfectly.  However, it does oxidize and turn yellow after a few months.

I loved this case when I first got it. It was very sleek, but over time the clear edges turned yellow. Dust and diets somehow got trapped behind the the case. I still love that I can have protection on my phone without covering the pretty rose gold color of my phone.
