So many uses

I use this for everything! Back pains, muscle cramps, comfort when sick, etc.
Use it at least daily! It does seem to “turn down” when it has decided that it has gotten too hot which is sometimes annoying as the heat dissipates when you need it, but still does the job

I have terrible cramps during my cycle and this product has been a great help. I've had this item for about 4 yrs now and, month after month, it has not failed me.
I don't place the item directly on my skin because I'm paranoid about equipment malfunctioning, so I use it over a shirt. I'm also certain the directions state the same for use anyway.
Overall, great product. When she finally gives out on me, I'll return for this product or to the same company for an upgraded model.
