After buying two cheap no-name batteries at large "Internet auction site" I had of such junk sick. A battery was to get only with the tongs from the battery compartment, the second was "only stiff", but had an abysmal capacity. Since the original battery seems to have evaporated with gold dust price structure after, I want to make up my mind with this product for the expected trade-off between price and quality. After a few charging cycles has this "compromise" does not confirm, because the performance of the battery has exceeded expectations and is the original I feel that in every way. As it is with the life, of course I can not yet see, but in terms of duration and accuracy is clearly five times the thumbs up. Top product at a fair price!
