The idea is great. Having a mirror on the back is a really nice feature to be able to quickly give yourself a quick glance or to make sure a selfie looks right. I've dropped the phone a few times and it's always survived without issue...my only complain is that it turns yellow and fades fairly quickly.
I bought a second one after the first started to discolor and the second one is already starting to do the same.
It's cheap enough that I'd probably buy it again but I'd look around for a different version from another manufacturer to see if another similar type may look nicer longer.

So, I upgraded my phone from a 5c to a 6s. I'm not really big on phones; I just needed a new one because my old one wanted to retire without my permission. Anywho, I recall ordering a phone case on here for my 5c and it was really similar to this one. However, I would recommend this case over my old one any day and here is why:
-This case is bendable plastic and fits my phone like a glove: My old phone case had two parts-- the non-bendable plastic holder and a semi-bendable plastic slider that slides from the back. My old case was horrible because the slider was always loosening and never stayed in place. But with this case, I didn't have that to worry about.
-Easy access to plug in ear buds and charger: With some phone cases, I have experienced difficulty when plugging in my ear buds and charger. I have had to literally cut some cases just so I had easy access to plug stuff in, but with this case, there is no difficulty.

Cons:
-I read a review on here that says it scratches easily. It does. I thought maybe the "glass" part had a plastic wrap on it that needed to be removed, but it doesn't. Because of this, I somewhat scratched it. So yes, scratches appear quite easily so be careful.
-I somewhat do not like the clear plastic look on the sides. Perhaps they could have had some shinny look for the sides (the same color as the glass on the back) instead of clear. My phone is silver and my case is gold and you can definitely see the silver part of my phone on the sides.

But overall, I like this case. It was affordable and it is protecting my phone.

I am pleased with this phone case. It looks very nice on the phone and believe it or not it's very protective for me at least. I drop my phone all the time like a bar of soap and nothing has happened to it so far. The case is flimsy and so far have just one scratch but it arrived without flaw.

It fit my iPhone 6s with no problems at all. Charger, headphones, volume control and power button all work great. The openings in the case are slightly bigger than the iPhone, so no need to worry about anything not fitting snug. Great price and super shiny! Please keep in mind to leave the protective sticker on the back of the new case. Preserves your shiny mirror longer.

Worst Product Case Broke in less than a month and half use with normal condition. Don't buy waste of money.
