Yup I use this one https://www.amazon.com/gp/product/B0...&psc=1&fpw=alm
I use it on a digital thermostat on a carpet/rug. Love it.
I do use a small fan with it as well to circulate heat. I find a big variance from top to bottom of the rack if I do not use the fan. https://www.amazon.com/gp/product/B0...&psc=1&fpw=alm
