The product is exceptional. My 8 year old son was able to submerge himself in the water. We'd had to cancel his sports camps for the summer due to his broken arm. The swim cast saved our summer. We still got to enjoy both river and lake activities. The cast did not cause any itching. I believe that sweat was washed away while my son was swimming. For this reason, alone, I think all casts should use this technology.I was disappointed, however, that customer service did not help to get my next day air shipping fee reversed. I had to drive 70 miles each way to the nearest UPS store to pick up our package in time for the Orthopedic appointment, 3 business days after the order was made. The shipping fee was nearly 3 times more than the padding kit. Also, the doctor recommended that I order two more kits to be used over six weeks. My son healed after only four weeks leaving me with an extra kit. I'd like to return the extra kit but, return policy lists only damaged or incorrect orders.
