I read the first few reviews on here and decided this product was a good buy. I couldn't have been more wrong. After a few days of usage it started to charge for a second, then stop for a second, repeating on end. I've read some more reviews, and it seems this is a common problem. Though it seems other people are satisfied with this product, so my advice would be to stay away from a product with such an evidently high percentage of lemons unless you feel like rolling the dice.
