Pros: that battery is simply great: - It last longer than a genuine Lithium battery it seems. - It comes well protected in a nice looking case. - instead of the "Indentation" at the bottom of the battery this one feature a little strip to remove the battery easily from the phone. - you can't beat that price (well if you except the advertised "genuine oem" replacement battery sold by ETE that are said to be bad)

Cons: the battery offer a better battery life than genuine Lithium battery, but I am not sure that it reach the advertised 2000mAh or the genuine Lithium offer better capacity than their marked capacity

Other Thoughts: the website is in chinese. I do not care if the battery is a real one, but I hope the battery is protected...

Bottom: you cannot beat that price and the capacity is higher than original battery. mine ran 6days without fully discharging in my old ngage...
