Have been filing my chainsaw chains for several years and although it seems to work 'OK' and I know all the benefits of filing I just can't be bothered wasting an hour of my life sharpening the thing every time I want to 'quickly' fell a few trees and cut a few branches. I'm already aware that using one of these will greatly reduce the working life of my chain but I'm keen to give it a try as I just can't be stuffed filing those damn teeth by hand anymore, urrgghhh.
Anyway, seems to be a decent unit with ultimate adjustability so for $91.20 Delivered I thought I may as well give it a go. Thought it may be beneficial for others too.
UPDATE Just found a similar if not identical unit for $75 from SWARTS
How much does just getting a new chain cost?
