I have a new pool and my pool builder gave me a quote for a GLI Max Shade mesh cover. I wanted to get at least one more quote so I had the local pool store come out and give me a quote for a Merlin Smart mesh cover. The quote from my pool builder is $2200 more than the local pool store. The GLI cover has a 25 year warranty vs a 15 year warranty for the Merlin cover. Is this a situation where it's worth $2200 more for the longer warranty? Is the the GLI cover that much better than the Merlin cover?
