After the first four weeks (Ionian, Greece), I can tell you that I've been very happy with the anchor so far.
Before that, I had a Rocna, same weight, which partly didn't dig deep enough due to the bow. In smooth sand, this causes the anchor to slip; In the case of sea grass, the anchor collects the grass in front of the bow. Attached is a photo at 10m water depth, sand, one minute full throttle astern. The anchor is always clean when it comes up and turns 99% in the right direction.
