Pros: it works. the back case that it comes with matches the shiny black on the i777. and the phones been used for 2 hours now (screen on the whole time) and it dropped 2% so far. time will tell on how long it lasts, both for total battery time and for how long it lasts.
Cons: the case makes it thick, but that's not a big problem.
Other Thoughts: the shipping said 3-5 days with a 1-2 day processing time. i received it 3 days after i placed the order. which is really fast figuring most stuff i order here takes at least a week. to receive.
