I have 2 homes in different states so I have 2 of these machines. It is quiet and you feel the effect right away. I was having problems with fluid retention in my ankles and this really seems to help. I was a little sore the first couple days but that went away.
I’ve had it for a week, it seems to work as promised, but this seems way too early to be posting a review for something that’s supposed to be a lifestyle device. Hoping for years of use!
