Not sure about how this performs, as it was a gift, but my brother was happy with the idea of a neck rub and deep heat while he drives in the chillyColorado winters!
It works incredibly well on the couch- I would fall asleep driving - awesomeness!
Great product , high quality - I wouldn’t use it driving unless I was driving to Mars and needed to chill - two thumbs up 👍
This device has been a godsend for me....I’ve always had a very stiff neck..:but 15 minutes with this thing and my range of motion dramatically increases! Thank You!!!
