This is a great product. I'm on my feet walking concrete floors 40+ hours a week and doing a lot of lifting of heavy objects. I use this massager while I'm watching TV and it really reduces soreness and relaxes tension. The only reason I don't give it 5 stars on quality is that there is a narrow open space under the top that covers the motor where material can get caught in the motor and jam it. But this massager is more powerful and therapeutic than half a dozen others I've tried over the years.
