I’ve only used this device three times, and it already stopped working properly. The first time I used it, it worked fine. When I set it to level 3, the device heated up as expected, and during shaping mode, I could feel the electrical stimulation. On the second use, the device stopped heating and wouldn’t heat up again until the battery was completely drained. On the third use, even the shaping mode no longer produced the electrical sensation, and the device was not functioning properly at all. After only three uses, this feels like a complete waste of money. I expected the device to work consistently and last much longer than this. Plus the battery couldnt even last 10 minutes!
