The product exactly met my expectations and fixed my running toilet. My wife is happy so I am happy. I'm glad I spent some time watching YouTube videos showing exactly what is involved, I like to know exactly how to approach a project before I begin so I don't waste time solving problems others have already solved. That said, when the videos mentioned that getting the thing to click into place on inside of the tank was a little tough, they understated things considerably. There isn't a whole lot of room in there for big hands and I was unable to get it to click into place until I used a long flat-blade screwdriver as a lever to coerce it into place. Start to finish, including time to utter some cuss words and go to the garage to get that lever was about 15 minutes.

When trying to replace the big washer to stop leaking in my toilet tank, two of the tabs at the base broke. I was concerned about the fit and looked at the photos very carefully. This one fit perfectly in my KOHLER toilet tank.
