It's plastic!  I would not have such a junky faucet in my kitchen. I  read the product description and reviews carefully and believed I was getting a brass faucet.  The description is misleading. It says "solid brass construction." The only parts of this faucet that are not plastic are the faucet piece and the handles. If you look at the attached photo you can see that all the other visible pieces are chrome plated plastic (See circled areas). And the parts that are not seen are plastic also.
