“I bought the DryPro half arm cover shortly after breaking my hand. The cover worked perfectly as advertised, keeping my arm and cast completely dry even after hours completely submerged at Princeton Hot Springs in Colorado. When I lost the blue vacuum bulb, I thought the sleeve would be totally useless. After trying unsuccessfully to find a replacement bulb on eBay, I contacted the company. Not only did they provide a replacement bulb – they shipped it priority mail so I would have it in time for a family pool gathering the next weekend! These guys (and girls) are the best! Thank you DryPro!” -Jerome N.
