Worked wonders for a indoor birthday party. Kept the cold cut buffet and salads nice and chilled after 4 hours in 72° temps. Even after the ice melted in about 2. We had no issues with leaks or problems draining it and deflating. Each one held about 4 8x11 pans and we only used about 10lbs of ice in each one. Only issue we had was inflating the one because the seal was stuck shut. Nothing putting a little wood skewer in it to open it up couldn't fix. They even came with a small patch incase one sprung an air leak. Will definitely be using these for further events.
