This product is junk I lost some weight using it I purchased it in Feb 2018 I started using it in June 2018 It stopped working in March 2019 contacted the company the one year warranty ran out in Feb 2019 so If I want It fixed I have to pay for the repair they think the wires that hold the pads are bad I used it 9 months the way they suggested for what the modias cost I would think I should have been able to use it for at least 5 years with no problems I have lost 10 pounds since it broke and am still losing weight without the modias that is why I say It is JUNK DO NO BUY IT!!!!!!!!
