Just got the case yesterday. I like it, but its certainly not perfect. Looks great, fits great, high quality feel and even smells good. QI charging works fine, too. I know some people are having problems with earpiece volume being too low on their phones, but I haven't haven't experienced that, and the case doesn't seem to affect call volume or ring volume at all, even though it covers the speaker.
The plastic window really, really sucks. All its good for is monitoring activity or incoming calls. Almost impossible to use the touch-screen through it. I tried to answer a call today by pushing the green phone button, and the phone just kinda locked up, even after I opened the case. The button lit up like it was working, but the call was not answered. I ended up unintentionally hanging up on the caller. Also tried taking a picture, but you have to press the screen to hard, so I'm trying to learn to use the volume keys for that, which isn't nearly as user-friendly for me.
I'm afraid I don't have a steady enough hand to cut the plastic without damaging the case, so I guess I'm going to live with opening the phone anytime I want to do anything with it. Still like the case overall, just wish they wouldn't have advertised features that really don't work well or at all.
