one of my son's bought a Iphone 6 case to protect his phone it's been working good so far I hear that some people have purchased these and they leave behind a coloring on there iPhone

Sadly I did get the yellowing with this case. Will not be buying another!

Unlike the other reviewers, I didn't experience any yellowing with this product though I've only had it a few days. I found it be a really good case. I liked the clear look of it, so you could still see the details of the iPhone through the case. It did a really good job of protecting the iPhone when I dropped it and I experienced no breakage.

The cover is stiffish rubber, but also slightly flexible, which seems to protect the case when dropped. Good product!
