Query: Gambled and won!

I must admit after seeing mixed reviews about this product I was skeptical. I decided that the low price was worth the gamble as I was tired of my cell phone battery constantly being dead.The battery looks official, charged easily, and has performed flawlessly. I don't know if I'm lucky or just biased because my old battery was pathetic. In any case I am very satisfied with my purchase and recommend getting this battery if you need a new one.
