I purchased this in 2017. Within 6 weeks the touch sensor was not working properly. Same issue as many of the reviews here. Delta was great and sent me a new solenoid assembly. Because of the sink size and disposer, it was impossible for me to replace myself, and I paid a plumber to come back out and replace the part. Now about 2 years later suddenly the water flow dropped to a trickle. I tried cleaning but to no avail. Delta was great again, and walked me through getting the water running by disconnecting and bypassing the solenoid assembly. They are now sending me another new assembly. This should not happen on a relatively new faucet. As much as I love the faucet and the touch activation, I can't recommend this product. The customer service department is great and very helpful, but this should not be happening.
