Worst Quality ever

Water stains very difficult to remove, It looks dirty only to run water, scratches with a spoon. I replaced my 6 years old and this looks worst in 2 days. I chat with Build Fergurson and "Sadly" after your install, they can't do anything, was very expensive, how you can know if the sink will be like this if you don't use it. Refer me with the manufacture, I follow the manufacturer's instructions and look the same, and also they can do nothing after you install, on top of that I spend $200.00 to install it, I really regret didn't buy for a big chain.
