I have for years used the Sanitas SEM 40, compared to more compact design falls but above all, the dream to use on. The last used program is started by pressing 2 buttons, then the intensity should only be set. The operation when switching between Tens, EMS and other programs is easy and intuitive. The adhesive electrodes keep with me now about 20 applications long. I have a time to clean the electrode base with water, because the Hafkraft ran after. After that Elektroben glued amends. The tiny part stimulates the muscles surprisingly strong and can carry on the work under clothes without any problems, for example. Buy recommendation!
