Hoping to be comfortable taking my Amazon Kindle poolside, I got these bags (9 X 6) before vacation. Since the Kindle measures only 5 3/8 inches by 8 1/4, it should fit.

Wrong. These bags measure only 5 1/4 by 8 3/4 inside the zipper.

They do a great job keeping out the water, just don't plan on putting something that is 6X9 into them. 2 stars

When placing Aloksak inside your checked in luggages (where your luggage get's squeshed pretty hard) avoid putting rectangular metal objects like a spare battery (PDA, Cell Phones) as the edges of these objects would cause pin holes - this happened to me but the seller sent me a replacement. So 4 star for excellent customer service. 4 stars

I bought these recently for an adventure race involving a lot of water and mud. I used the larger one for a big map folded in half, the mid size for a information book, and the smaller for a cell phone (I bought several different variety). All three bags worked flawlessly being submerged completely under water at several occasions and through multiple zippings and unzippings. These are a very high grade of plastic and are constructed very well. These aren't anything like the space bags I have that can't hold a seal for more than 15 minutes. 5 stars

I used the smallest size sak (9x6) for a recent adventure race. I liked the smaller size (easier to hand carry) but the next size up might have been a little better. Fortunately, our map was small enough to fit in the small sak. 5 stars
