The electro pads only work when they want to. Also- contacted seller about not receiving cord set for the grey pads and seller has yet to contact me back.Thank youI have received my product , I am pleased with it. It was worth the wait. Once again thank youAnnieI am very disappointed cause i was super hype to use this machine but The suction is very , very ,very weak and it’s missing components to use tension pads ,not sure that machine is bad or if the suction really super weak like that , but maybe it’s not that weak and the machine is just defected i really don’t know , took 3weeks even though i paid for expedited shipping . I’m not happy with my purchase and have requested a refund , still waiting on a response , i paid too much and waited too long for the product not to be right ??????No instructions, can’t find manufacturers instructions. I’m a licensed esthetician and love my 7 in one machine that does laser lipo/body cavitation. I wanted to incorporate this but very disappointed cause I haven’t been able to use it. I Put together what I could with the ems connections and have minimum feeling of the electronic tens unit pulses. Haven’t been able to use cupping part because unable to tell which part goes where.This product is the truth!Todo esta bien solo que los plásticos que ban a un lado no venían y según me los iban a mandar pero no e resivido nada ?
