Delivery came as always quickly and without damage. The material is really very good and noble. The sink is heavy and feels more like stone than plastic. The reviews about broken faucet holes had intimidated me somewhat. My opinion: impatient to act, wrong technique.
A little tip: with 3 masonry drill along the grooves many small holes drilled! Then the break points resolve. With arrows the hole can then be filed round. Takes 10min.
