Summary: It's well built and while being on the heavy side, it's lighter than a lot of models using similar materials. It's classed as a pro model and I don't see why some professionals wouldn't get the standard they desire from it. I think because of these points, Slik could possibly get away with pricing it slightly higher. Maybe no higher than £150, but £122 takes it into the lower classifications.
Pros: Clever compacting design on handles, Inverting centre column, Excellent build materials
Cons: No spirit level, No quick release plate lock, Shoddy quick release lever materials
