Here's my 2 cents worth 
:
Pro:
1. broadband filter will be useful for bigger & brighter emission nebulas like Orion Neb, Lagoon Neb etc, filter can be retracted for normal use without filter
2. wide AFOV
Con:
1. not fully multi-coated lens coatings
2. not Bak 4 prisms
3. may have astigmatism & barrel distortion in the outer 30% field
4. may have ghostings/reflections on bright objects
5. short eye-relief
6. a bit heavy
7. not waterproof
