The faucet had fairly easy installation, and shows good performance. The 1.8 gpm aerator gives a little less flow than I'm used to, and the flow with the new faucet is a bit "solider" (less diffuse and aerated) but less strong than the faucet it replaced; I tend to prefer the flow of the previous faucet--but the new Delta seems certainly okay (though a bit noisy, perhaps). And I also hear this new kitchen-faucet's flow through the pipes of the shower in an adjacent bathroom, which wasn't heard with the previous faucet; haven't yet found out why that might be (not evidently from any leakage).
This review sounds critical, but (other than the curious flow sounding in the wall 25 feet away when it runs) I'm happy with the faucet. Seems like a good design, especially with the diamond-coated valve.
