Works great.
Great tool. Catch a small lithium 12v battery online and solar charger to keep it charged or plug it into a power port on vehicle.

Great tool
Once I set it up for the correct blade it cut down sharpening time to a quarter of a hand file. It comes with a 3/16" stone so buy a few extras or different sizes you may need for the chain saw blades. This has a threaded shank on the stones so make sure you get the stones with a thread not the ones with a 1/8" unthreaded shank. I used "Oregon 31401 3/16-Inch Threaded Chain Saw Sharpening Stones 3-Pack"

Every chainsaw owner needs one.
My last one died after 20 years of use. I can sharpen a 24” chain in about 5 minutes saving $15 or more that the hardware store would’ve charge each time I use it.
