Woah, that drop test hurt me actually. :) There are many alternatives on such product, I think to get ahead they should've put more time into design. It would look better with a slimmer batteries, since they already designed for a specific phone model, I don't know why they didn't designed the battery part better. Anyways since these phones costs a fortune these days, it's always better safe than sorry.
