Some of you may have already found this but it is a new find for me. It is a Hygger Titanium Heater with IC Temp Controller. What got my attention was that the set temperature range goes up to 104 F. It comes in several different wattages but I got a 50W to try. The heater does not have a built in thermostat but it plugs into the controller that provides that function. The controller has a set temp and a sensor to measure the actual temp and displays both. Not sure how well it will work or how reliable it will be but I thought it was worth a try. I just plugged it in in a 3.5 gallon bucket of 67 degree water. I did get a chuckle out of reading the instructions. And Yes, it is made in China.
