What is Reddit's opinion of Milescraft 1201 Base Plate/Bushing Set for Routers?

From 3.5 billion Reddit comments

Yeah, that use case came to me right after I called it in to question. That does sound perfect if you're a door installer.

But, yeah, it does look like you'll have to either fabricate a baseplate, adapt a full-size router baseplate like this one, or build new jigs that reference off of the edge of the baseplate rather than a bushing.

Ryobi also makes one. I can't find any direct info, but it looks from the picture like the stock base might accept bushings.
