Although I was very displeased with the turn around time of my order, I do have to say that the Seido Innocell 1500 Extended Battery is fantastic! With the stock battery I noticed that my touch pro would get a little warm during use, with the Seido Battery it doesn't appear to warm up at all. It sure feels like I am getting more than a 10% improvement in battery life from this battery. I highly reccomend it! .. Fits the phone with no extra bulk.
