This works perfectly for me. I read my Kindle while floating in the pool and recently spent a week at a cabin on the River, and spent a lot of time reading while floating. The closure works fine and it really is 100% waterproof, as I discovered when my sister accidentally rammed my float with her kayak, knocking me into the river. Luckily, the case also has a neck strap, so I didn't lose my Kindle! It's very easy to use the touch screen and on/off button through the case. And it arrived very quickly - I ordered it 2 days before I was leaving for my trip, not really thinking it would arrive in time, but it came the morning I left, so I was really delighted.
