To be honest, this thing looks like something that would come with the iphone because I believe it's similar to those ipod slip pouches they come (or used to come with). It's made form the same material the iphone wiper and it's awesome! I've tried many cases and skins and they all deteriorate the natural beauty of the iphone for me. Then I realized the thing is super durable under normal usage (unlike my psp which is very fragile). So I use the thing naked and I decided to buy this to preserve the look of the iphone when I used it but at the same time just keep the screen sealed up so I doesn't rub against my pocket (which is probably fine, but it just feels safer in this!).
The one concern I had with this thing is that you would probably want to put this on upside down to hear the ringtone. I tried it right side up and it turns out you can hear the ringtone fine because the sleeve isn't a super tight fit on the iphone so you can hear the ringtone just as normal. So for those of you don't want a lot of bulk on your iphone and just need a simple protector (but not drop) to keep in your pocket, this is the perfect thing!
