Oregon Rail's Signals

Has anyone tried Oregon rail’s signals or crossbucks?
Are they any good?
Would they be suitable for a UP equipt interlocking?
Or any other good suitable makes?

I’ve got a bag of the dwarf signals - 10 signals per bag. They are single-LED, dual color units (R/G). They’re working fine for me. I’ve got them on the frog end of my turnouts to indicate position.
