I run it at 42.0 W, that is just a little higher than the suggested 40W. Actually the cotton they give you is quite thin and you have to use 2 or 3 of their pre cut pads, Instead I use the thicker Japanese organic cotton pads, I cut them to size 0.5 x 0.6 in and use 1 pad. I bet what I use is considered 3mm they come in 60mm x 50mm squares 10 per bag.
