My biggest concern was whether the intact arrives. But when the package has there been someone really rough mischief with, so what happened. Much Styrofoam, a rock solid board and yet solid wood as a direct protection to the water's edge. Much better it gets. Next hurdle: the penetration of the holes for the shutter operation and the tap. Again ... very worried. This is after all a relatively brittle material! I've placed the sink to their destination and embarrassing pay attention, which is the worktop is 100% straight. Thus, the sink was on all around. I think the problem that some had penetrated during the drilling was simple, that was the sink either on trestles or otherwise, where she too has a certain bias. Did then the hammer and a punch used ... set ... beat ... NOTHING! So something courageous ... ... SHOCK POCK ... works! The rest of the material I've removed with the Dremel and a flap wheels, but works only partially, as the material of the sink is similar to the coating on the sanding paper and thus the grinder eats virtually. With a metal cutter or tile cutter it is gentler on tools. For the finishing touch you can then sometimes sacrifice a flap wheels or some sandpaper rolls. The installation of the drains is also easy, even if the instruction is a bit poor. But the most important information you can get and if you're not completely stupid folds. The retaining clips are also awesome ... very thoughtful. Even though I was able to use only 4 pieces in my design and the rest is just in black silicone. But this is definitely attributable to my kitchen. Little hint yet ... if the countertop is really flat as a pancake and you worked clean: very little silicone around. Otherwise wipes you look stupid and dimwitted, until it looks totally clean. My concern, which had not come off the silicone residue on the sink unfounded. The can be Dry rub off (I had, however, worked carefully and only a thin silicone veil left on the sink). Oh, one more thing. I thought that part would be harder. My parents have a sink made of ceramic that looks similar, has cost 700 euros and is unable to cope alone. However, the shock sink can affairs well. Conclusion: I am delight!
