Right on Torch...you really do get what you pay for. The make and model are'nt readable on mine, I think its fairly old. It is the submersible kind and I can regulate it to a degree or two. The regulation is according to my other thermometer which is always floating tin the must in the primary stage.
I've been really happy with mine, like I said, the temp is right in the range I wanted for fermenting. I've seen the belts and I think it would be a lot easier to use a submersible aquarium heater than a belt. For the money I think they are the same price, heaters being glass, I was in love!! Mine is the 25 watt and takes a few hours to raise the temp of a full 6 gallon primary, but by the time I'm ready to pitch yeast, I'm at the right temp. I also like how it is regulated with a thermostat on the unit, The little light comes on when the element is on.
Like I said the purists are probbably laughing their heasds off.
Just my thinking
