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.

After purchasing my liner from this company, and the absolute amazing customer service received after I had to return it because I got the wrong size, I would never shop for a pool supplies, anywhere else! The quality of the liner , the price, the customer service and the speedy delivery cannot be beat

This was the wrong size for us but we got the 27 foot and the pool is filling as I type! Install went very smooth, of course it's our third or fourth time installing a liner. Thanks for great customer service! We were disappointed that we are stuck with the wrong side and can't return it! 🫣
