I'm very satisfied with SilicOne, which is a shame because it needs to be reapplied annually. There is a refresher course available, but it costs just as much as a new coat.
Easy to install, no configuration required, obviously. Poor reception, both inside the boat and outside in bright sunlight. No satellites detected, approximate 50 meters, signal listed as poor and unusable. I returned the product, which I assume is defective; it can't be that bad.
I was able to replace my existing sink (size 11) with this – very welcome after about 18 years. No accessories are included, which wasn't necessary. The old sink had been badly damaged.
The new sink is sufficiently sturdy. HOWEVER, the surface is only brushed, so there's no high-gloss finish. At this hefty price, one would expect that.
