I am currently renovating a house in the week and am a keen outdoors-person during weekends, so my phone has tolerated its fair share of abuse. Having had a few close-calls with dropping phone, etc, I decided that the standard silicone-type cases just weren't cutting the mustard any more.
Whilst this case does beef up the phone's size slightly, its still just as easy to handle and feels natural in the hand.
I have been very weary of these types of cases, having used them in the past, incl otterbox, etc. I have found that they restrict the phone considerably and make using the buttons and the phone in general cumbersome and difficult. Not this one - its easy to fit and is built in a way that accessing the screen, buttons, USB port, etc is non-restrictive.
I can't speak for the belt-clip as I've thrown it into a drawer, however, the case feels and looks solid and satisfying like it means business. I would highly recommend this case.
