I think you are talking about the end of the fill when it shuts off. That will change this summer when the water gets warmer. Hopefully you will get used to it and not notice.

Installed easily and works well. Water level is exact at each set point. Only issue was whistling as valve was closing for the first 2 weeks. No longer a problem.

I use these in my horse waters. They work great and I was so glad to find that Home Depot had them in stock for much less than the feed and grain stores.

May not be code compliant in your area
Home Depot review 4/15/2020 for the DANCO Anti-Siphon Fill Valve, model 80008. Although stated to have anti-siphon technology, toilet fill valves with submerged check valves are not code compliant in many locales. The relevant standard for anti-siphon compliance is ASSE 1002. To avoid potential issues of a device failure resulting in toilet water backup into the water supply, or to avoid issues with home inspections, one might consider one of the commonly available Fluidmaster or Korky valves as examples of units that are code compliant
