I have a Husqvarna 3/8" roller guide set like that, iffy at best.
Round and flat files are better that Stihl's, the file holder is really nice.
The roller guide is questionable though as it is made to fit a specific chain chassis.
I had issues with the guide not setting over Oregon Full Skip chain, so I had to file the guides notches wider to slip over the chains tie straps.
Then I noticed that the round file does not position equally under the cutter on different brand and model loops as they feature differences in tie straps and tooth height - it often positions too high generating a slow cutting chain.
The only positive thing about this Husqvarna guide is it works on semi & full skip chain, which the Archer FastFiler doesn't.
No hate here, it just didn't live up to expectations.
I try many guides in the pursuit for easier sharpening and faster cutting chains.
X-Cut 3/8" is a great chain, even simply round ground!
Currently my favorite.
