I wanted to write a quick note to tell you how happy I am with my Blue Onyx device! I steered away from microcurrent for years because I thought it was difficult to learn and use…nothing could be further from the truth when it comes to the TAMA!!! The software walks you through each treatment , so there is no longer any reason to be apprehensive! My first day with the device I did 4 treatments….so, thanks so much for making this technology so simple and user friendly! I LOVE it!!!!!!!
