Before I go into the details, I wish to make an overall assessment. The PRORELAX Nervstimulator 39263 Tens + Ems Duo is a compact easy to use device with high functionality. Review: Packaging of: small, handy Kunsstoffkoffer, inside with individual compartments for the equipment plus accessories => very good solution. Manual: concerns good, comprehensive description of what TENS. EMS functionality is not sufficient for me, but was not the desired functionality. Housing and Controls: very stable, handy case, sufficiently large display with all the necessary display. Operating buttons with borderline size (not suitable for sausage fingers) Use of the instrument: I bought the device for the treatment of my right shoulder and my wife - elbow problem. Previously SUPER treatment success after just few days. Can only recommend the device. Value for money: very good Recommendation: Buy
