Its ok, but I wouldn't go nuts. It did have its faults without going into all the tiny details I wouldn't buy a copy electrical product again. It is not a samsung, it looks like one but nothing on this phone is in any way similar.
Takes a bit of getting used to but once you know how to use it, its fantastic. I am a cyclist as well as I don't like a lot of body hair so this is just the best piece of kit to go from the chest to my toes in one charge.
