Are you tired of persistent muscle pain, post-workout soreness, or relying on medication for relief? Look no further than our FDA 510K cleared dual-channel TENS & EMS devices—the AST1009 and KRES-100B.
Designed for home use, rehabilitation, and active lifestyles, these portable electrotherapy units deliver professional-grade pain management and muscle stimulation at your fingertips. Whether you are an athlete seeking recovery or someone managing chronic discomfort, our drug-free pain relief solutions are engineered to meet your needs.
Both models combine Transcutaneous Electrical Nerve Stimulation (TENS) for targeted pain relief and Electrical Muscle Stimulation (EMS) for muscle recovery, strengthening, and rehabilitation. They are ideal for anyone seeking a non-invasive solution to manage sore muscles or improve mobility without pharmaceuticals.

While both devices deliver exceptional performance as a muscle stimulator machine, their designs cater to different user preferences. Use this comparison to decide which unit fits your lifestyle.
