Review: Perfect for finishing 3D prints - I bought this mainly for post processing my 3D prints and it's been exactly what I needed. The 22000 RPM is plenty of power for sanding down layer lines, drilling holes, and cleaning up support marks on PLA and PETG prints. The cordless design is clutch when I'm working on prints. No cord getting in the way or having to hunt for an outlet near my workbench. Battery life has been solid, I can usually finish several prints on a single charge. Size and weight are great for detail work. It's way more comfortable to hold for extended periods compared to my old full size rotary tool. The grip feels good and I have way more control when I'm trying to smooth out fine details without overdoing it. Came with a decent variety of bits which is nice. I've been using the sanding drums mostly for smoothing prints and they work really well. Haven't had any issues with the bits coming loose or wobbling. Speed control is smooth and consistent. I can dial it down for delicate stuff or crank it up when I need to remove material faster. No weird vibrations or loss of power even at lower speeds. Only thing is the battery takes a little while to charge but that's pretty standard. I just throw it on the charger after I'm done and it's ready next time. If you do any kind of finishing work on 3D prints this is 100% worth picking up. Makes the whole post processing workflow way faster and the results look cleaner.
Review: Nicely designed set. - Great design, and construction feels pretty solid. Magnets in the case are not strong enough to keep it stuck on my metal filing cabinet. Tool itself is a little loud and the slider is not super precise. But having a cordless rotary tool is very useful.

### ⭐⭐⭐⭐ PERFECT TOOL, except not UNIVERSAL BIT SIZE
*by H***I on August 24, 2025*

Would LOVE to give it 5 STAR! Innovative, powerful, ergonomic, quiet, and FUN! Own several grinding, polishing tools, but nothing beats this one when it comes to ease of USE. ONLY ONE ISSUE there’s no spare heads as far as fitting other larger MM bits/mandrels. 2.35MM isn’t universal. Make sure you buy extra bits/heads in the correct MM.
