Battery Full [Q] Has anyone purchased these extended batteries?

So my stock battery hasn't been giving me the battery life that it used to, so I'm looking for replacements. I went on ebay because that's where I got my batteries for my OG Evo and I came across these. Since they have been purchased so many times, I was wondering if anyone here has purchased them and could tell me what they think.

Thanks guys.
