Zynex Medical has been steadily increasing the pressure on physicians by offering various forms of payments, rental of office space and meeting rooms. Company stock offerings are also suggested thus increasing sales volume which gains the attention of investers. These practices are going relatively unnoticed but it's just a matter of time until the Feds catch up. For anyone who would like to offer TENS their are reliable companies out there but please don't fall victim to the Zynex "bill of goods". The reps are aggressive (by training) and unrelenting. Remember, don't put your practice at risk the benefit of a "fly by night" company.
