I bought a new treadmill and was really bummed that it kept shocking me. It was happening about once every couple minutes! At first I thought it was an issue with the treadmill but after researching I learned this is quite common due to the charge you accumulate while running on the deck.I found some things folks recommended, but I wasn't fond of strapping my wrist to the frame or dousing myself and the machine in fabric softener so I rolled the dice on this very affordable product. I was quite skeptical regarding it's effectiveness, comfort and durability.I'm so pleased to report that this thing is much higher quality than I had expected. Time will tell, but it feels quite sturdy. Seriously, even if it only lasts a couple months, it's a bargain. Comfort-wise, I can't even feel it on my foot! I run with high stack height, max cushion running shoes and while the heels are quite large, the thing strapped right over my shoe.Most importantly, it works! I went from constant shocks to absolutely zero! I just have it on one foot, by the way.I don't write many reviews but I hope that other people with the same issue I was experiencing will find this product. I'm just so thrilled it actually works and I have no complaints whatsoever.
