...yet I've used many hydrofarms for years and they're all still going strong. Any thermostat can fail*. Sometimes it's not about how it will be cheaper in the long run, but shelling out a large sum at once. Someday I will have a Herpstat. I know they're quality products. However, I honestly haven't seen a reason to upgrade at this point.
