Comments about 30mm Control Block, Double:
Unfortunately, but this has nothing to do with the product itself, I ordered the 30mm which are to small. The line fits and it does the job, but it gets jammed easily. It is not possible to return and order new (bigger blocks), because I live in Dubai. With my next order I will order bigger ones.
