It's a great tool. The Stylus is not really a substitute for my AC-powered, digitally controlled, Dremel 398 Pro, which I use for heavy-duty work and can put in a desk-mounted holder, because the Stylus and all battery-powered units lack the torque and speed control of the heavy-duty Dremels, but it is much easier to hold and far better to use for precision work because of the pistol grip design. For work on hard materials where you need torque and speed consistency under load, such as cutting steel, get an AC-powered unit; but for precise control over bit/burr placement, and work with plastics and foam, there's probably nothing better than the Stylus. I do wish it had an even lower low speed, but 5K is the lowest speed available.
On both my Dremels, I have changed the collets to the keyless chuck, which I find much easier to use. The Stylus battery lasts a long time, and charges pretty quickly.
