We had silestone installed. Seems had to be redone. They still look bad. Recently a dish fell out of my cabinet and chipped the counter. No! It's NOT covered under warranty even though it's only two weeks old! And yes, it shows EVERY water mark, smudge, etc. And I even use a special cleaner for it. Silestone is all hype and definitely not worth it. And their customer service is terribly. Our installers scratched my brand new stainless sink and now they won't make good on it.
