I was amazed to find this little tool is so much more powerful than the equivalent Dremel. Won't take all the Dremel accessories, like router bases and stuff, but for such an inexpensive tool it is great. I keep one in my work van for those things that only a Dremel will do. After a couple years of cutting off small bolt heads and similar tasks and other abuse this wasn't really meant to do, the flexible coupling inside disintegrated. Cost a dollar each for the two replacement parts I needed and its back up and running. The Dremels I've fried over the years don't have any replaceable parts internally that I could find. Nice little tool.
