Dear Massagemag team, this is Chris from Achedaway (https://achedaway.com/). We are a technology company developing massage therapy products such as percussion massagers. All of our products have been undergone lengthy tests to ensure that they can suit most fitness levels including professional athletes. Our major product is a smart electric cupping device (for cupping therapy), distinguished from traditional cupping tools with the advanced DYNAMIC CUPPING TECH. This tech provides rhythmic alternation of suction and release to bring the best results of the stimulation of acupoints and boosts blood circulation faster to the cupped area so that it speeds up the muscle recovery process. This product is mainly used for relieving back&neck&shoulder pain and muscle soreness. In addition, by using this product, users can have a cupping therapy on their own at home lying down on a bed even without a professional therapist, because the App control offered by this product can almost free their hands, and they can switch the intensity levels and suction modes to tailor their own need based on their current physical conditions like having a highly experienced cupping therapist. We would send you more info and free products for a thorough test if you are interested. Thank you!
