Giving this 5* because it exceeded my expectations! I’m a paraplegic, so I used this sitting in my bed. I’ve had so many ooh/ahh moments already! The fabric is very cool, smooth and comfortable next to my skin - it does not get sweaty or sticky. The motor noise is minimal and kind of soothing. There seems to be only two actual movement choices - and there’s not that much difference between the two. Also, there is no detectable heat from the “infrared light”. But I’m not deducting any stars because the massage it does give is so wonderful! I can have it go as deep or as gentle as I want without getting tired out - the design is genius! You put your arms through the holes and away you go. Also, while sitting in bed, I put just my hands in the holes and can pull the massager from the lowest point to about mid back - then I switch to putting it around my neck and work down to mid back. I can go up and down, as hard or soft as I want. I discovered that if it hurts in one spot, just go lighter there, and keep coming back to it - going deeper and deeper. My whole back was full of knots and this little gem is working them out - and this is just the first night! Because of my condition, I can’t lay flat on a masseuse table, plus I would have to Uber or ask a friend to drive me to the chair massage place. I have ALREADY got my money’s worth!!!! This is a game changer in my comfort level.
