Avazzia BEST devices are the premier electro-stim FDA-cleared non-pharmaceutical, non-surgical method for symptom relief of chronic, intractable pain and adjunctive treatment in the management of post-surgical and post-traumatic pain. Devices are engineered and manufactured in Dallas, TX. Avazzia was founded in 2004 to engineer and manufacture advanced, innovative devices that are hand-held, easy to use and feature patented biofeedback technology and software. All devices use two AA batteries and can be used with accessories. Avazzia's product line includes: PRO-SPORT, designed for use in clinical settings with advanced frequencies and options; BEST-RSI, for clinic use or at-home treatment; and BEST-PRO 1, perfect for patient use at home. All three require a prescription. Also in the product line are ezzi-lift, a cosmetic microcurrent device used for facial massage to gently and naturally stimulate the skin's own production of collagen and elastin; and BEST-Vet, used by veterinarians, ranchers and animal owners.
