The product fits well enough but when pushing the phone to it's limits (playing complex games, running several apps etc) the phone does tend to get hot without the case, and needless to say the case only makes this worse.
This is not the fault of the case, just something to keep in mind. When charging for example I tend to slip the case off.
Also, somewhat obviously, the case being silicone the phone is much more secure in the hand, but a bugger to get in your pocket as the case grips the cloth of your trousers!
That said it does protect the phone from my inept and clumsy ways, and that's what I needed it for.
