Needs very neat, but not for each sink

However, for each sink that is obviously not what. I have a simple stainless steel sink, and there is the fitting due to their size and the massive construction is not particularly stable. The valve rocker / shakes a little - no wonder when the lever which acts on the thin sheet. The solution in my case was that, in addition to securing the valve under the sink with a bespoke elbow on the countertop.
