Review on Pain Relief Made Easy: Thermalon'S Effective Moist Heat/Cold Compress by Jason Childs

For me-the design flaw is that each section doesn't maintain the same amount of beads, they all slide down because of gravity. For instance I'm using this on my knee as I sit up in bed but then I realize it stops being warm because all the warming beads have slid off to either side and the section covering my kneecap now has like 10 beads in it but the side sections are full. I wish the stitching went all the way across each section to keep uniform heating all around.
