I wanted to give my experiance with the new herpstats that spyderrobotics has recently released to the general public.I am very pleased with mine and was lucky enough to buy the very first one directly from George .The one i bought was to be used for my natures spirit incubator and since its made specificly for incubators it made things easier.So if your looking for a perfect thermostat i suggest looking up spyderrobotics
