Really great case, fits like a glove so congratulations to incipio for a quality product. Feels sleek but not slippery in the hand. Not only does it fit perfectly, the aesthetics are spot on too, which when you are covering up a phone as beautiful as HTC One is important. I've read a few reviews regarding volume control not being easy to access but I must say I haven't had any trouble. So impressed with this product that I bought the Dual Pro Grey/Grey too.
This case has a really nice feel to it. It offers great protection without sacrificing the HTC one's slim and lightweight design. Also, the carbon fiber back feels amazing and doesn't slip out of my hand. I definitely recommend this case to anyone who likes the executive look.
