Over the years, I've owned a number of Criterion scopes, several of which (all Newtonians) were quite good, optically (don't even think about one of their SCT's!).
With these scopes came a large number of Criterion eyepieces. Without exception they ranged from "pure *Word deleted by the CN gnaughties gnomes*" (the Ramsdens, Kellner, etc.) to "just not very good" (Orthos).
Maybe there' someone out there whose experience is more positive...but I've never met that person.
Hope this helps!

I have 9mm and 18mm ARs that came with an RV-6 that I recently purchased. I don't use em much, but IMHO they are decent eyepieces. Yes, the field of view is narrow, something around 36-38 degrees if my memory is serves me half decently. But they are reasonably sharp and they do not seem to have ghosts or other such problems.
With my RV-6 I normally use a set of Meade Circle T Orthos plus an similar vintage Meade Circle T MA-40. The scope does a nice job all the way around but the views in the MA-40 are quite amazing. Very sharp across the field of view.
