We installed this faucet 3-4 years ago, and we're on our third cartridge. The faucet leaks from under the handle and when we woke up in the morning the whole counter was wet. Fortunatley,, I'm handy, so I could do the repair myself. I can only imagine what a plumber would charge. The reason I updated all the plumbing in my house, is so I wouldn't have to do plumbing repairs!
