We used it in the Balearics a few years ago. It wasn't as superior as the claims suggested (highest copper content of any antifoul paint) but it was no worse than several others. At the time the big bonus was that it was delivered to the boat, ashore on the hard in Palma.
Been using it for 5 years and am happy (Danish waters, mind you - low salinity)
As with other thick paints there is a tendency to build up which eventually will take a total removal.
I'm not there yet but after a removal I'll swith to a thin-film version to prevent build.
Thin film on my radar just now is SEATEC Antifouling GTI 30 @ EUR 89.95 for 2½ ltr. from svb in Bremen, Germany
Compared to eg. VC17m @ EUR 260 for 2 ltr. the business case is clear.
EDIT: Being a online operation only, run by one man as per his idea of customer relations and supported by a son (?) pushing for a more modern approach, the experience is a bit different to other operators in the market.
Used it a few years ago when yacht was in Sardinia and then Greece. Delivery included. However me along with 2 others had issues with a batch. To Bill's credit he sent out replacements (at his cost............of course) but when ordering the next year was told that EU45 could no longer be delivered to Greece due to airline restrictions! Found it to actually be worse in Greece than the local stuff which I now continue to use.
