Product review (3 stars): OK quality - works - needs some added parts
Not the highest quality product (made in China), but it's OK, works and does the job. All plastic construction and for the price, I thought the quality should have been better. Maybe it's not supposed to be part of the kit, but there was no washer/grommet to go between the switch and the sink where it mounts in the hole in the sink top. Without a seal there, water can leak around the switch and get down under the sink. Being a DIY'er I just used some Plumbers Putty to seal it up when I mounted the switch/button. Also; even though there are threads at the base of the switch and at top of the relay box for a lock nut/cap to hold the plastic air line in place, there were no caps/nuts to do that. Over time either end of the plastic air tubing could come off the nipple (on the switch, or on the relay box) causing the unit not to work. But as I said, it works and does the job. The transaction was easy and the shipping very fast.
