Good tool
Very nice little tool with a decent selection of attachments. Would have liked some finer sanding heads and a variety of drill bits but still fundamentally a good product

Streamlined and compact.
Well designed, more attachments than I’d know what to do with. Come with case and compartments for tools. Charges quickly. Did every job I needed it to.

Nice, well made. Could use more torque
Well made, quality item. Good weight and well balanced. Could use more torque which would make it more versatile through the speed range. Saying that it served my purposes well in cutting through 1-2mm carbon fibre which was done at the 3rd speed setting upwards (It has 5 speed settings) to much force it would cut out, I would have to turn it on and off. Once I got use to it and used it lightly without force it did it’s thing really well. Battery life isn’t to bad but ultimately that depends on the size of the job your carrying out. I would recommend this rotary tool.

Cool
Can't remember why I bought this but I can't recommend it enough. I loved it so much that I bought extras in case the one I already don't use breaks.

OK for price. Good quality.
The tool is a bit bulky and on the heavier side, but nothing unmanageable — still perfectly workable. That said, it could be tiring for people with smaller hands, especially during longer sessions. The price is very reasonable for the quality and what you get. The speed switch works perfectly, and the “wireless” charging is a nice touch. You just sit it in the cradle to charge, similar to an electric toothbrush, which avoids constantly plugging and unplugging cables. One thing to watch is how you seat it in the charger — it uses two contact prongs, and a few times I didn’t place it correctly when finishing work. My biggest gripe is the on/off button placement. It’s located at the back, which is a bit awkward. I’d much prefer it closer to the spindle lock area for easier access. Another downside is the lack of torque at low RPM. I sometimes need to trim plastic at low speed to avoid melting, but with this unit the motor stalls if you apply even light pressure at the lowest setting. It’s missing that bit of low-speed torque you occasionally need for controlled trimming. Despite these flaws, I’m keeping it and will continue using it. For the price, it’s still a decent tool and does the job well enough.

What an awesome tool for the price. And also excellent packaging/storage in a zippered, custom fitted faux leather case. I wasn't expecting nearly this nice a unit for the price. The tool is very sleek looking. It runs smoothly and seems quite powerful with 5 discrete power (speed) settings. The included accessories are numerous, and each has its own divided section for storage. The charging cradle plugs in via USB-C (included) and the tool simply sits in the cradle for charging. There is an LED light lighting the work end of the tool as well. Very nice product!
