Kohler Margaux K16230-4 Centerset Bathroom Sink Faucet

We have had this faucet for about 3 years now, but for the last year or so most of the when used it leaves water under the round part around the handle. Would we need to tighten something or replace a gasket??? Otherwise am satisfied with the faucet

Got the polished chrome. Looked like a million bucks! (when new). The shaft became discolored making it a bluish tint in areas. It also has been hard to keep clean due to water droplets sitting on the flat area of the arm(won't drain off) and around the base of handle after using. But the worse problem is the chrome wearing off on the edges of the arm !! Really? As much as this costs!!! And I only used plain water to clean it. No harsh chemicals. Only had it 4 years . At least Kohler replaced it. Not sure how long before the same problems return. Maybe a brushed finish would hold up better.
