This is the second order I have placed for a total of 4 of these units. The first one I tested worked fine for about a minute then ran full speed no matter what the pot setting. The second unit seemed to work fine, so I ordered 2 more. Again, the first unit had almost no speed variability and got so hot I got a burn from the solid state heat syncs. The latter unit seems to work fine. I am getting about a 50% working devices. I must say the ones that work, seem to work well, but disappointed that half of what I have ordered doesn't work. I recommend ordering 2 if you want one to work!
