I have been using rotary tools for over 50 years. I have a few rotary tools on my workbench, but all but the Proxon are regular weight, meaning I need lighter tools for my older hands. I looked at the specs on this little car and thought I'd give it a try. 5 of my Proxon, I already put it on "my tests" and its performance is comparable to my Proxon at the moment and I think maybe it's a little lighter, THAT means it's a keeper! FWIW, I was taught decades ago. It's money, and you'll save TIME by storing different bits in separate tools, and SAVE $ by not switching bits without downtime! So I have 3 rotary tools with THREE different cutting attachments that I use the most!
