This waterproof protector is the best invention ever. Shortly before our summer vacation, our daughter broke her ellbow. At the internet I came along bloccs.com and looked the promotional film. Then I have ordered the protector immediately, but in Germany, because I needed the protector quickly. it's a blessing, that there is this protector, he keeps absolutely tight, you can swim and dive. if you put it on,you do it the easiest with two persons and with two straws can protect easily pull into a vacuum, so that he also bears well. this protector should be recommend to all orthopedic surgeons know really worldwide. If you ever broke your arm of leg and you warnt to take a shower or you like to swim, buy a bloccs waterproof protector, it works!
