Review on WaterSeals Locking Backpack + Waterproof Bag for Women & Men | Ripstop Material & Anti-Theft Lock | Protect Wallet, iPhone or Valuables at Beach, Pool, Skiing, Camping by Hugo Caywood

I bought this for travel with the idea that I could secure it around a sun lounger or tree branch when swimming and not worry too much about someone just picking it up and walking away with it. I'm glad I bought two - one for me and one for my friend because my lock didn't work at all - luckily it worked! We used it for the reason given and we really liked it. Not as strong as me. hoped, but again he has achieved his goal. Unfortunately I see I've just missed the return date after returning home from a trip, so I can't return a broken one for a replacement :( Check your locking mechanism before going on a trip!
