I'm a cook with a lot of work experience. Most of the day I spent working with my head tilted down and the years I have acquired a chronic muscle pain in the neck area. When searching Google, I found one site and bought the Derma Roller Applicator Massager. Later on the beginning week of regular use I could feel a change for the better, after a month the pain allowed me. Today I feel like a normal person and I can safely recommend this product to others. I'll be happy to share my experience with others.
