Review on DonJoy Cryo/Cuff Cold Therapy System - Gravity-Fed Cooler With Tube Assembly For Effective Pain Relief by David Banks

I love the fact that I can prepare this to be used in less than 10 minutes. Just fill the jug with water and ice, wait about 5 minutes (or less) for water to be chilled. Attach it to the cuff and it is ready to go. Once the cuff is full of water detach the hose and you can walk around if needed, but I recommend sitting with the injury properly elevated. After about 30 minutes you can drain the water back into the jug then refill the cuff and it is ready to go again. I have been able to use this for 4-5 hours with one ice preparation.
