After losing my cell phone to a lake while flyfishing i decided it was time to try and avoid that mistake. I LOVE this guy i actually bought another one of these (a larger size). I can pretty much let it sit beside me in the water and it will float and not take on any water. It is the best enclosure for valuables. I took this to a theme park where i knew there would be water rides and it still protected. I also used this on the beach to protect my phone. It kept my phone out of the sandy elements. I recommend this product. Any questions please ask i am always looking for advice so i enjoy giving it when i can as well.
