Exactly, I've got 3 ve-200s and I love them. My snakes took a **** last February which stunk up the house... (This was about 10am...) and my cousin opted to open the window instead of calling me to clean it. it was -27celcius outside, and just about -20c In my room, the thermostat kept my cages exactly where they needed to be.
They are amazing little devices

I use the pulse option for cages, and the constant flow of electricity for incubators,
