Bests & Worsts Reviews from Amazon

Great to handle, decent battery life, decent pressure. However, I'm not sure how, but after using the pointy tip on myself, I found that several spots in arm and back had been skinned. It is painful now, and I imagine it will be until the skin grows back. I will contact the manufacturer. UPDATE: I contacted the manufacturer who explained that I must have used the cone tip at an angle. So, do not use on self. I wish that I would have seen a warning, but I believe there is none. They were gracious enough to send me a complimentary roller, and a dual tip head.
