It's been about a month since I bought these motors. Some experience is needed behind this review, not first thoughts. So yes, they do get a little warm. They didn't flash or catch fire, but that's enough that I don't trust them to turn on overnight unattended. Excellent rotation speed, around 2-3 as advertised. Easy to assemble and assemble. In fact, I have a feeling everyone does it. By price? Take her. The glass can usually stop spinning after 1-3 hours depending on factors and the epoxy should not shift on you. A few times I let it spin for 7 hours, checked them out, and they seemed to "survive". Great for a start if you want to taste water on the fly without investing too much. Happy turn!
