Works fine. A better deal than Amazon.
It works as advertised and I verified it uses 22 watts. Heating pads do not feel warm to the touch as
they are below 85 degrees and the human body is 98 degrees. An on/off switch would be nice.

Just buy it !
This TDS pen is wonderful. The back light is green and when a stable ppm is detected it turns red. You can read it live or press the hold button to save it. Auto shut off timer. I love it.
