Great product, we have other Renpho products, so I’m very happy with their quality. This feels very weird at first as it inflates (sounds like an auto blood pressure machine!) and farts the air out. Haha. The warmth is nice and it does feel like it benefits. I’ve used it about 3 times now. Purchased to see if it will help with dry eye. Time will tell. The music is ok. Overall I’m very happy with this. Easy to charge with supplied USB cable.
