I paid £80 for this item, from an Amazon subsidiary site (A1 Deals), about a month ago. It's a lot to pay, but I don't mind paying premium prices for top quality, reliable equipment; after all, it is a Sony product. I used it twice on my Sony camcorder, but the third time, it would not charge at all. I know that it is the battery unit that is faulty, as the original battery, supplied with the camcorder, still works. Judging by the feedback left on this product, you've got a 1 in 5 chance of getting a dud! If you can't trust Sony, who can you trust?!
