Product review (4 stars): Worked as I expected, pretty easy to install.
This was easy to install and worked as expected. The switch fit into what was the sprayer hole. The tube connecting the switch to the unit was easy to cut to size. The only real challenge was attaching the unit to the side of the sink cabinet (screws not provided). The power cord must be about two feet long. which was long enough to allow be to plug this switch into the outlet for the oven which was just to the right of the sink cabinet.

The switch works with less pressure than I expected.
