So after looking at the Draco bumper ive been itching to get one. But I thought wouldn't it look much more sleek with a carbon fiber back. Black on silver on carbon fiber. I looked around and I found one that came with water tight seal on ebay for a few bucks. I dont know if it is truly will seal the same as oem but i figure it will probally help withstand a accidental 5 second drop in a sink or toilet vs a battery cover that has no seal at all.
