The liner arrived very quickly. I think two days after I placed the order the directions were good. The liner went on just the way it should've I believe. Got it filled with water and enjoying the pool. Thank you for your quick service and quality product.

Not only does it look great but the quality is wonderful and the service was above and beyond. I initially bought the wrong size and they gladly exchanged for the right size. The shipping was super fast and my account got credited the day the wrong liner got back to them. Im very impressed by everything!

It's been many years since I last bought a liner for our 18 ft. Round aboveground pool. You guys were very quick in shipping my order. Received everything no damage boxes. I can't wait to install it in late April to early May. Would love to tell you more about that timeline. Thanks.
