Received mine today, very soft and flexible, I can wrap my wrists, feet, leg, or lay it across my back. The size is very large, I'm 5'4" and it spans from my shoulder down to my wrist-it's 12"x24". I love that it's machine washable, but since it's made of soft materials I say the gentle cycle and damp drying or air dry should be used. Giving it 5 stars: moist heat (spray pad with water), variable settings (warm, low, medium, and high), and 2-hour auto shut-off all are awesome features to have. I'm actually sitting on it now, aaahhhhh!I'm currently going to therapy for my wrists, they've increasingly became more painful, I don't have carpal and I do have ganglion cyst that was noticeable on the right hand that now shrunk, it was huge the size of a nickle. My left wrist suffers from pain as well but does not show a ganglion cyst rising. If therapy doesn't' take the constant pain away, surgery is the next option to suck out the gel within the tissue that's causing ganglion cyst - not liking that.Anyway, my occupational therapist uses moist heat therapy with microwavable pads (sandwiching my wrists in between) and as well, utilizes ultrasonic/heat machine to massage my hands and forearms afterwards; the process relaxes the tissues and firms my wrist overall, he said my carpal was loose and all over the place. Since seeing him for a little over a month now twice a week, he says the carpal area is much tighter and becoming more stable (I can't even do push ups without my left wrist feeling so week) but I am nowhere near a carpal tunnel surgery; good thing cause my mom had surgery on hers.I still have pain but I'm coming along nicely.So I figure I'll speed up my healing, along with maintaining the health of my wrist by being proactive and apply some heat therapy with this pad at home not just the twice a week at my therapist's practice. Plus, I have upper back and shoulder muscle cramps from sitting in my home office for hours at a time so having this heat on my upper back/neck area will loosen those tight muscles up as I work! Another use is for my tail bone and butt area cause I sit so much the muscles hurt after awhile. I also plan to use it while reading my devotional in bed before going to sleep just to lullaby my body tissues and relax them, I can only imagine how good I will feel after my gym nights.So many uses for this heat pad. I have a tens unit as well (that I bought here on last year for about $30 something) and this is such a complement to eradicating pain with out the use of pain killers.Great product and very well made.
