Overall, I am very satisfied with this sink and faucet. The sink is very sturdy and the sound proofing was not expected. The spray button on the nozzle feels a little cheap, but matches the price of the sink/faucet combo. Not sure if it's a feature, but the base the the handle is attached to rotates. I have verified that the nut under the sink is tight. Neither the threaded part of the base or the flange on top of the sink rotate,  just the section where the valve is. If that is a feature, I would give it 5 stars instead of 4.
