Rancos, Johnsons are the two top of the line on/off thermostats and are perfectly fine. I have two.


Helix and Herpstat are the two top of the line proportional thermostats and many people prefer them for racks and incubators. I have one.

Both brands work well for me and do what I need them to do - which is to regulate my temperatures and protect my animals.

Hope this helps!

By the way, be sure you order the wired Ranco!
