My daughter broke her arm (Supracondylar humerus fracture) a week before we was going abroad. The waterproof full arm protector was amazing and completely saved our holiday!! The sleeve didn't leak once and we used this on and off about 3-4 times a day for 10 days until the seal had stretched too much. We ordered another to come by airmail which only took 6 days to arrive at our hotel. Would recommend to anyone! Thankyou Bloccs
