champiOnline Waterproof Multipurpose Case Cover for Cell Phones, GPS, PDA + Many Other Devices + Free Mini Stylus Pen

I got this waterproof case so I could read my Kindle Fire in the tub. It works great! The case seal's tight with a series of 3 zip locks, and then snaps with buttons. I don't think I would fully submerge it the water, but I feel very safe that my Kindle is protected from the water while I'm lounging in the tub with wet hands. Great product, plus the price was very reasonable.

Nook is very hard to get into the case, very tight fit. Also, touch screen barely works when in the case. It is definitely waterproof though.
