Query: Battery arrived in a timely fashion and seems to be good

I've had this battery for about a month and, so far, it is working OK. I'm usually a little skeptical when buying batteries online, but who is going to pay the retail price? For this product, the price (including shipping) was OK and the battery seems to be holding a charge. I have it installed in a phone that is seldom used, so it's a little difficult to evaluate the quality of the battery.
