 >> I used it this morning to control the heater element on my coffee maker - the coffee maker element is rated at 1440 W at 120V, and a Kill-a-watt registers 1420 from it. If set to non-variable mode the kill-a-watt registered 1410. When switched to variable, the output was as follows: at the lowest setting it output 687 W, at the middle of L it output 710, at the top of L: 750, at mid-M 812, at low H 955, and at the max the Kill-a-watt showed 1374 W. My desire was to reduce the output of the coffee maker to slow the brewing and it worked perfectly for that. The unit heats up whether in variable or non-variable mode, in variable mode it does get hotter, but not excessively in my opinion. Your mileage will likely vary... >> I used it this morning to control the heater element on my coffee maker - the coffee maker element is rated at 1440 W at 120V, and a Kill-a-watt registers 1420 from it.

-The above reviewer was able to vary the power from 48% to 97% of the normal measured power by adjusting the controller's knob.  +The above reviewer was able to vary the power from 48% to 97% of the normal measured power by adjusting the controller's knob. Note that **at ~50% power it will take about 2x as long to brew the coffee**.  Maybe you want that, or maybe you are willing to put up with it to be able to squeak through at 710w instead of 1420w.
