So to anyone who is expecting this remotely fast, I wouldn't get your hopes up too much--I'm on the second full week of waiting since my 2000mAh battery shipped and I still haven't gotten it. It'll get here eventually >.>
And to everyone that is freaking out about the price of this battery, you have to remember this is made for a completely different phone--I'm pretty sure stock batteries for TP2 (and the other versions of that phone) are 1800mAh. If that's true, 2000mAh isn't much of a stretch, especially if its a LiPo battery like someone said. Anyway, it isn't going to melt. If anything it'll probably just have a much shorter overall life than a better brand of battery (as in you might have to replace it after one year instead of two years like a better brand).
Just a thought, I'm not saying I'm right.
