I really like mine. I love having a naked phone, because I hate cases that make the phone bulkier. I don't drop my phones but I do accidentally put things in the same pocket sometimes so I wanted something to protect my screen. I had a screen protector on my S3 and hated it, they are fingerprint/oil magnets and scratch VERY easily, so I could see myself replacing it every couple of months.
This flip cover protects the screen while in my pocket or if i lay it down somewhere and it adds very little bulk ti my phone. It is a little cumbersome at first to take pictures but you get used to letting the flap hang while you take pictures. I also like that it protects the camera lens while you are using the phone and have the flap flipped back.
It doesn't protect the top, bottom, back or sides of the phone so if you drop your phone a lot this is not for you.
