The Ostabelt works amazingly. I have had an ostomy bag now for three years. Its extremely uncomfortable when I exercise and walk too much. I always felt as if it was not secure but when I tried the Ostabelt, it sure fixed that problem. I’ve been able to move more freely and exercise ten times harder since using the Ostabelt. It secures my ostomy appliance in place so it enables me to move freely without worries.
