Review: Great replacement filler that is fast, quiet and easy to install. - I have installed 3 of these in my home in the last few months, and am.wsntimg to do.the rest. They are so much quieter when filling and do not bang when they shut off, which typically is amifoef by copper plumbing. Easy to install, adjustable height (though difficult to turn the knob), and once adjusted to.height, work nearly silently without issue. None of them have leaked at all, and have been very dependable so far. Again, I plan to do the rest, so they are all as quiet as the 3 I have done.
Review: Simple and well worth it. - Very easy to install, no adjustments needed, and straight forward installation. I will replace all my fill valve's with this one.
