Bests & Worsts Reviews from Amazon

Works well, and definitely helped out peppers sprout more quickly (within a week this year, compared to 2-6 weeks last year with no heating mat.) As others have said, one of the LED segments in the display of the thermostat burned out pretty much immediately. I can still tell what it's supposed to say, but if you're a perfectionist, this may bother you. It doesn't affect the functionality. EDIT: Within hours after leaving this review, Vivosun reached out to me with an offer to replace the thermostat. When I inquired "how," they replied with "no worries, already on its way." Phenomenal customer service, and highly recommended! That's truly rare these days, and I will be a repeat customer. Review changed to 5 stars. EDIT 2: A new thermostat was at my door this morning (2 days after communicating with Vivosun customer service.) Absolutely outstanding; they've made a loyal customer out of me. Highly recommended.
