Review on Wahl Deep Tissue Percussion Therapeutic Handheld Massager – Powerful Pain Relief for Back, Sciatica, Neck, Legs, Feet, Shoulders, Muscles, Tendinitis, Arthritis - Gray Metallic by Nicholas Gendron

This thing doesn't shy away from the power department. This will certainly move some tissue and blood. In fact, you probably don't want that thing high up if it's anywhere near your spine or neck. I also like the fact that it has many. Devices that allow you to focus or distribute energy. The only thing stopping me from giving all 5 stars is a small but important flaw in the design. Instead of being on the back or side of the massager, the combo power button and speed dial are on the working side. For example, if you're working on your shoulder blades or mid-back, there's a good chance the grip will hit your shoulder right where the wheel is and slow everything down -- or even disable it entirely. I love and still use it regularly. But I feel like nobody really tried to USE this thing when they designed it. Seems such an obvious little mistake.
