It does its job very well, I bought it for sharpening a milling chain as my 2 in 1 stihl sharpener is set at a different angle. It is finicky at times to get set correctly on your bar, but once set, will sharpen each tooth the same in no time. Not as quick as the 2 in 1 sharpener but I suppose you can't have everything. I would suggest looking at the electric version of this if you plan on using this whilst it's on the chainsaw mill. Quality of the product is good, but as it is mainly plastic it would not stand up to much abuse. Chainsawbars were great to order from and would not hesitate recommending them.
