This is my best wellness purchase to date! it´s like having your own personal massage therapist. The unit itself is rugged and sturdy and ergonomically designed to reach those difficult areas of your back with ease. The control knob allows you to gradually dial the pulsing action from low for very gentle relaxing muscle massage to high for a downright rough pulse that will pound out any soreness or tension after the most rigorous/strenuous activities, and have you feeling like a million bucks in just a few minutes!
Good quality and very soothing relief especially for backpain.
