The unit is very good. Thanks to the clear display, the operation is very simple. An improvement in symptoms occurred after a short time. Also, the storage problem of cables and electrodes is cleverly solved. However, the supplied electrodes are good very little, despite thorough cleansing of the skin, the electrode did not adhere properly and dropped off at the slightest movement. The electrodes were moistened, they held during the therapy time of 15 minutes on the skin. Nor do I believe that the replacement electrodes are better. The unit has 5 star worthy that not a single electrode! Therefore, a total of only 3 stars.
