I recieved one free from Verizon because they didn't ship me a normal battery after trying out a droid charge they let me try beacuse I went through 6 refurb tbolts. Had to go back, the tbolt screen isn't as good, but in almost every way it is faster and more capable. I love this extended battery, I don't have to charge it all day and it lasts from morning to night. At first I said I didn't want one, but I am very glad I went for it. And by the way, my tbolt works flawlessly, was going to upgrade but why should I? The tbolt does everthing I need it to do and works great. For now I will save my money and continue to enjoy a great device that goes all day on 1 charge.
