I think I have the same anchor as you it’s made of Aluminium.
I have not used mine so also would be interested to hear from anyone who has.
The review of this version of the Fortress are good.

I have a 7kg Manson Supreme rigged to deploy from the cockpit. Never had any trouble getting it back (so far).
I also have the original 1.9kg Fortress as a kedge. I've only ever used that as a beach hook having dropped the Manson and rigged as a running mooring. The Rocna and Manson style anchors do work very well.
The recommended anchor sizes are often a bit on the cautious side. Depends a lot if you intend to anchor during a storm or just for a few hours over lunch. You can get holding force figures from anchor suppliers but they will include a significant weight of chain. As a guide here are the loading figures for a Mac based on various scope lengths and wind speeds:
