The product itself is first class. The guide is very accurate, you can meter the pressure fine, and the ferrule is neither delicate nor too weak to meet the needs (I'm working with wood, and for this material are forcing that have been designed for the construction site, too heavy). Also no distortion should be noted, which is remarkable in this 60cm and slim design.
However, dispatch is a joke: I ordered once and once a three ferrules (after consideration of the first), and I took four - again, FOUR! - Packages in reception, each of which would have taken about 30 clamps of this type. They varied between flat and square-up, the packet form for table columns and gun barrels. I imagine better.
