Bests & Worsts Reviews from Amazon

OK so for what I am using the bag for it works fine. That being said I did a bit of an extreme situation test of the product to see how water proof it actually is. I placed a few dry towels in the bag and rolled/sealed it up, I then held it underwater in the bathtub for 5 minutes. During this test I noticed air bubbles escaping out of the seam, so after 5 minutes I removed the bag opened it up and voila' the towels were all dry. So like I said for what I'll be using the bag for an underwater test was extreme because I will not be using it in any situation to which that will happen. But if air can get out that means water could possibly get in, so for people using this product in mass water type recreational activities be aware that if this product happens to be underwater for a significant length of time than the items contained within may potentially get wet. At least longer than 5 minutes. Now I tested the smaller electronics bag for 10 minutes underwater and to be honest I didn't use any electronic device, instead I substituted with a piece of paper towel which worked as a perfect test medium since they are very absorbent materials and would provide proof of any leaks at all. After 10 minutes drum roll please...voila' dry as a bone, not even any escaping air bubbles. All this being said, if you have some cloth items and they get wet that is annoying and inconvenient but you can hang them up and they will dry. However if you have an electronic device and it gets wet that could possibly lead to a very expensive replacement, not as simple as hanging out to dry. If 4.5 stars were possible I would give this product a little more credit but c'est la vie.
