After getting the Samsung A900M I found out about the poor battery life. Saw a few other people recommend this extended life battery. Since it was a fraction of the price that Sprint sells it for I went ahead and got the 3 pack, since I also needed the travel charger and a secondary wall charger.I'm glad I did! I actually think the wall charger fits better in the phone than the original that came with the phone (contrary to another review I read about the quality being cheap). I like the way the cover looks on the phone, even though it makes the phone a little thicker.I have not tested the car charger yet but expect that for the price of this 3 pack it will be everything plus more than what I expected.I highly recommend anyone needing the extended life battery go with this deal. ULTRA cheap and worth every penny!
