I bought this faucet in the middle of last December. Liked it a lot. 
But now it does not have water come out of the faucet. It is terrible at this time that we need to wash our hands all the time. This faucet only worked for less than 4 months. 
I contacted the customer service, Candice was nice and sent me an email for how to fix the problem. But I do not have any tools to do it and are not good at this kind of house work. I am waiting for the tool and a cartridge that was ordered for me then I can call them again to get their help to fix the faucet. 

I had a previous Delta faucet and it was installed by the builder 14 yers ago, it had no problem until last December, it also had problem to have water come out.
