Ya but I spent $12 and it works perfectly fine. Just a curiosity, how many snakes do you keep? Do you have a separate thermostat on every enclosure? Or do you use racks?
Right now I have a combined 52lbs of snake meat to heat up, in 5 enclosures. So ya $30 for a cheapo t-stat in every separate enclosure is a huge waste of money for me. Just to feed my 3 adult females it costs $36/feeding. Not to mention the other 4.
If ambient temps stay stable, and you monitor your enclosures closely, there's no reason why a dimmer/rheostat won't work. They worked for decades before t-stats became so plentiful and cheap.
