Our new faucet did not come with a flow regulator, so we had our plumber install these. They work great and do not make any noise. Perfect solution. I'm attaching a picture of the back of the sink vessel. This will prevent the water being turned up too high and splashing out.

I use these a lot as a contractor, my customer are happy with the look

I’m certain it is functional but I’m often disappointed by the cheapness of such objects. It seems to suit a trailer more than a house.

Great product and fast delivery...

This was the perfect product for creating a wall mounted water softener bypass. The quality is excellent. This is a difficult product to find, but Wayfair came through.
