I've been using Dremel for about 20 years so I have the necessary bits and bits. When my old tool finally broke, I was relieved to find this kit. It's well equipped with extra attachments, sanding discs etc, but doesn't duplicate things like the flexible shaft, 90ยฐ adapter and circle cutter that I already have. Didn't come with my previous kit but might look useful. I'm glad that this device has a separate on/off and speed switch, unlike my old device that combined these functions. I'm also glad that all the old devices I've tried seem to be compatible. The case is nice - sturdy and relatively thin - but it's overstuffed and doesn't fit all of my extra parts.
