Stihl, husq, and Echo are basically Gold, silver, and bronze medals for chainsaws. Anything else is likely made by Bohlens with a different label depending on the store that sells it, cheaper homeowner stuff that'll work for trimming a tree once a year, but if you have to use it more than once a month its not smart to avoid the top3.

How does it compare to a dremel attachment, do you know? I might get pic related, seems like every sharpener has its own ups and downs.
