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.

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.

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.

Actually a nice set and the tool works well for my 3D printed projects but I received an opened/ used set. The plastic wrappings were off and underneath the tool instead of wrapped around the tools. The casing is dirty and scuffed. The polishing paste looks like it’s been used. Expected a new set not an opened/ used one. (Update) 12.18.25 Hoto reached out to me and offered a solution to my issue. I was surprised and glad that they care about both their product and customers. Truly outstanding customer service on their part. Meanwhile, I’ve had a chance to use the tool for my 3D prints for a few days now, and it works well. I bought it mainly to use for my 3D prints, so I’m not sure how well it would stand up to other materials like wood or metal. I like the slider instead of a button to change the speed, and it’s thin enough to hold like a pencil. The case is not as organized as other competitors, but as long as the tool works and is comfortable in my hands, that’s all that matters.

Quality Mini Cordless Rotary Tool Kit. Powerful compact rotary tool.

Very useful and easy to use.

Poor quality design. The dremel tool has some resistance when sliding in an out of the chamber. There’s no slots to secure/organize all of the bits and accessories, they just sit loosely in each section. The door covers where they are stored don’t have a hinge. It’s more like a creased fold that over time can weaken and snap/break apart. After removing and placing the dremel back into its storage chamber, after the second time, the speed adjustment knob popped off and shot across the floor. Took quite a considerable amount of force to re secure the button back onto the dremel. Even sliding the knob from left to right the speed doesn’t increase until roughly three quarters of the way through. Overall quality and design is a bit lackluster to justify the price point for this kit. Switched over to a similar product by Fanttik for the same cost range and the build qualities between the two are worlds apart.

Major red flags right out of the box: - This bits do not magnet in place neatly as pictured in every single photo or expected in other HOTO products. Text this particular kit from something I do want to show people to something I do not want to show people. The photos do not match the product. - Extremely tight tolerance removing the tool from its sheath. Feels like I have to force it in and out and expect long-term aware on the product from its own case. Again, this is very different from the other two HOTO tool kits I have from the same line.
