Try the much much less expensive version first. It’s a shiatsu massager (Naipo) and it has worked GREAT for me, my mother in law, my son who has ice hockey injuries, and pretty much anyone who has visited here and used mine.
Walmart online still carries the brand I have (Naipo). $30 or less. I’ll send you the link PM because it’s long and screws up the page.
We have had one for years. Only use it gets is when grandchildren like to play with the remote.
