You sent me the wrong product. I decided to keep it in the hopes of one day being able to use it, but as I live overseas I didn’t have time to lodge a complaint, especially since the only way way to contact you is in writing. I even took a screenshot of the gel pads I ordered, where it described the pads as having a particular feature (a button that can be attached the these wires) and the ones I got were completely different and have no button and can in no way be attached to my TENS machine. Very unimpressed. I also got an email NINE days after ordering them, to say they had been shipped, despite the website saying that they would ship products over $20 the SAME DAY. Super unimpressed.
