I am an acupuncturist in a busy pain clinic and have been using the Alpha-Stim 100 for nearly three months. The first time I used the Alpha-Stim, I was impressed by the results. I have been using it every day since, and the results continue to impress me. With it, I have successfully treated all manner of pain syndromes, including back pain of all varieties, migraines, elbow pain, knee pain, shoulder pain, painful scars, post-surgical pain, and the list goes on. I have also used the unit successfully in treating depression, anxiety, insomnia, and fertility. It combines wonderfully with acupuncture and has greatly enhanced my effectiveness as a practitioner. Thank you for bringing this device to market and for your contribution to the medical cannon. Your product and your expertise have helped me to help many people.
