Peel were very kind to send over to me two of their cases all the way from America just so I could try them out and see what I think about them.
Hands down these are the thinnest cases I've ever seen for the iPhone 5 and iPhone 4/4S. They're made from your ordinary plastic but they're unbelievably thin. To get them off your phone you literally have to peel them off.
I've been using the cases for a month now, because I'll be honest, at first I was very skeptical and thought they'd tear or just wear badly. Boy was I wrong. The cases look just like they did the day I got them. Because of the material they're made from, it's pretty difficult to scratch them, you really have to look carefully and under certain light to see any scratches or wear. I can see over months of constant use that these cases would wear, but that's expected with most cases around this price range.
These cases will definitely not protect your phone from drops but that's not the point of them. They've been made to just protect from everyday wear and scratches. I myself am very careful with all my phones and have never actually dropped one so I've never been very worried about smashing one. However I do like to keep them in fantastic condition, I don't like scratching and scraping them whatsoever. These cases are perfect for someone like me who loves to feel the slenderness of an iPhone but protect it from everyday wear.
Weirdly the iPhone 4/4S case I found was smoother and I thought generally nicer than the rough texture of the iPhone 5. Not sure why the textures are different on the cases, but I definitely prefer the texture of the iPhone 4/4S.
