I was looking at PIDs for my star sizer with the Magma heater when I came across this on Amazon and Fleabay. I usually find myself switching the heater on and off depending on how fast I am sizing bullets, it really depends on if the machine is cooperating or not. If everything is running smooth then I need to increase the heat to keep up but then if I encounter problems the lube gets to hot so instead if adjusting the super sensitive Magma dial I just turn it off, essentially doing what this device would do for me. I am no electrical expert so I would like some input from those here who are because this seems cheaper and easier than a PID for the sizer heating plate.
