This was by far one of the best purchases of my life. Yes, it is basically just a super solid ziplock bag, but I don't care. I read my Kindle while sitting in a pool drinking margs in Cabo San Lucas and you didn't. My girlfriend also could not stop making fun of me. I have no idea why the decided that this product needed a strap to wrap around your neck. What is the possible point of that? Looking like a bigger geek? It is bad enough that I have to remember to pack 24 different chargers every time I go on vacation for my Kindle, iPad, Laptop, Phone, DS, Ipod, etc. but now I am wearing a plastic Kindle protector around my neck? That is just a little much.
I don't have any fancy video to add (although I certainly watched that review pre-purchase and then demonstrated the same thing to any friends who would watch). The one slightly annoying thing is it is hard to slide the power button when the case is on... oh well, I was reading my kindle in a pool! How cool is that?!?!?! Why wouldn't you want to be reading your books while in a pool, pools are awesome.
UPDATE 9/6/12: Well, thanks to a trip to the Bahamas, my waterproof kindle case is no longer waterproof. Don't worry my old Kindle keyboard is still fine. This terrible accident occurred, not when I was being attacked by the Hammerhead sharks at Atlantis, but instead when I couldn't find a bottle opener so i tried to use my kindle to open my Corona. Can you believe it was unable to do the job? Talk about a 1-star deduction.
Also, I was tempted to combine my love of in-water reading and my love of lazy rivers, but the aforementioned girlfriend nixed that idea, even after she bought her own waterproof kindle case (a cheaper ebay variety that seems the exact same minus the writing of "trendy digital" on it).
