I was a little disappointed with the heated gloves. The heating side of thing met expectations, but felt that the quality gets this product down. The batteries are very hard to fit into their pockets, this puts a lot of strain on the wire that is plugged in. Also to charge it uses a micro usb socket, which I associate with older technology as all new products have usb C fittings.
As already said, these do work ok, but I just wonder whether I've been sold old stock as the jacket I ordered a couple of weeks before has a usb C socket and the pocket takes the battery with ease.
