Very good quality and feels great on sore muscles and tired legs. I have only had it a few days so it’s a bit soon to tell on long term benefits but I have high hopes. I need to spend some more time learning the best way to use it to avoid rattling my brain- since I get a lot of headaches I don’t love that feeling.
I've only just begun using it but so far I'm impressed. Not like anything I've ever used before so I'm excited to see what long term impacts regular use will provide.
