I ordered this battery for my Pocketbook 627 (Touch Lux 4) to replace a faulty (not so old) battery. The battery came nicely packed and protected by bubblewrap. Dimensions of the battery were exactly as of the old one so I did not have any problems fitting in into the case, I only had to place it upside down due to the cables being on the left side. I noticed a slight difference in the connector as the new one did not fit the dock. It required to slightly scratch off a bit of the excess plastic on the sides of the connector with almost microscopical precision. Battery was charged at 66 % and was manufactured only a month before the purchase, which is both very good! I can recommend the seller and I also encourage those who are considering the replacement of a battery on their own - even an amateur can do it just fine. But don't forget you also need a doublesided tape to fit the battery in a place.
