RA Fisher company has been absolutely fabulous to work with! Our daughter suffered from hyperhidrosis and we tried many different treatments, but none of them seemed to work. Since she started using the iontophoresis machine we have noticed significant improvements. Our daughter is no longer self-conscious about her hands and her confidence has improved greatly! RA Fischer Customer service (Delia Hamm) is top notch and she was always willing to help out while getting started, as well as always available to answer questions during the treatment. They also went above and beyond in helping us getting the machine through our insurance company! A++++ company and staff!!!!
