Excellent sink, excellent quality! Have had no issues with this sink, and have had it installed for 3 years now. I wipe it down after doing dishes and have yet to experience the staining people mention. I bought this sink, an Edison kitchen faucet, and 6 other bathroom faucets when I built my house and am super happy with everything from Vigo! I can say I wish the bathroom faucets had a tad more pressure but it’s not a deal breaker. Looking at Vigo shower towers to replace the one that’s not a Vigo in my master bath when it’s time to do so as they didn’t make them when I built my home. Very pleased with Vigo and their products. Haven’t had to utilize a warranty or customer service as of yet but from what I read from other customers if I do it will be a pleasant experience!
