I purchased that one off of Amazon because my battery died so hard I was getting 15 minutes off of a full charge and needed faster shipping.
Turned out identical to the one in my phone but it lasts about as well as the factory battery does.
I would have purchased the cheaper option under normal circumstances, but was in dire need of a fast delivery.
Just watch prying your phone open, the phone itself damages easy. In retrospect, I would have purchased the plastic pry tool as well since my miniature flatheads produced some unsightly divots on the outside of my phone.
