I’m a plumbing contractor in Florida. Been plumbing for 20 plus years. I can tell you kohler is by far my go to product, especially for shower valves. The way they are designed makes working on them easier than most. (Everything needs to be repaired eventually). I like the Devonshire because of the value and quality. Not sure why other reviews were so bad, probably weren’t install right or lack of use will cause any shower valve to not operate correctly.
