No problems at all with the order & delivery of the battery. It lasts longer than the original battery when it was new. I was suprised that the battery is thicker than the original, so it makes the back of the phone stick out just a bit. I have not found that to be a problem though - the phone still fits just fine in my purse cell phone compartment and in my jeans pocket. It's much nicer to have the battery last for 4 days instead of 4 or 5 hours like my old one!
