If the main (ie: the cheaper) thermostat fails in off position, your rack goes cold.
Well the cheaper one is NOT the main thermostat, the VE 200 is. I used the cheaper one for at least a year and 104 reading would have my hot spot at about 96 and it is the backup. The rack doesn't go cold if that happens because it will turn back on once the temp on the probe of that particular ones. If the temp goes down 3 degrees it turns back on.
I can accomplish the exact same thing for $35.
It only cost me $35 but I preferrred the proportional one.
You spent well over $100 to gain nothing.
I gained a lot since the VE200 keeps the temps at a constant temp within a .1 degree instead a constant on/off. Plus I don't consider $115 well over $100.
I am really not understanding why people need to make this so difficult/expensive?
It wasn't difficult at all it was a choice I made and am really happy with. I had the hydrofarm one anyway so I wanted to use it
