have been running my johnson with no problems whats so ever for a few days now. I check the temps multiple times a day and they have stayed steady since i set the thermostat up. I will be purchasing a herpstat a.s.a.p since my other racks are almost done. So far i cant say anything bad about the johnson but like i said im only a few days in.
