We have had our pool since 2004. Only once I replaced the auto fill insert. It was not expensive. When I was thinking about it like you before our pool was contracted one or two people told me about stories they heard. It stuck and over willed the pool. We have never experienced this issue. Remember, there is a certain evaporation rate fir every pool. It depends on a lot of factors. One nice thing is if you leave on vacation you do not have to worry about the pool level.
I would not be without it. Good luck in your decision.
