Bought this a month ago and it was a dud. Never held its charge even after the stated 18 hours initial charging required. The battery feels very light compared to the genuine one, and so one has to wonder if the quality is any good at all. Well, now I know… When I emailed to complain, I was promised a replacement but that never arrived. Mighty Ape is usually good but this time this product is a fail, and service is a fail as the promised replacement never appaeared. So basically I have paid for a dead piece of plastic.
