I had read the reviews and just hoped I didn't get a duff one like some of the others. Guess what? I got one that will hold a charge for 24 hours, unlike the factory original that works for 3 or 4 days! Don't buy this one. Get the all white one. Having said that some have complained about that one too...maybe you just have to keep buying until you hit a good one. No doubt for the price of the "real" one you can afford to try a couple of times! Good Luck.
