I received that battery. Took probably three weeks (I was not really anxious considering the price.) I've been using it about a week. I've not performed any scientific tests to compare it to the stock battery. I use my phone randomly through the day, multiple voice calls of random length, checking email at random but at least once an hour, anywhere from a few to a few dozen texts, web browser a few times a day and GPS when needed. Throw in the random Midori, Groovefish, Facebook and pictures.
My general observation is that I'm getting approximately the same life as the stock battery. That's not what I was hoping for (considering the claimed extra power) but for the price I will not complain.
