As described

Just installed seems very strong and should protect pond liner for a long time at least that's the hope.

Finally a great liner from a great company!!!

I started my pond at the end of 2019. My first liner cost just as much as this one and it was half the size. It was to small and it tore easily. My second liner was 75 dollars more then this one and fit perfectly but I was patching it before it even had water. I got fed up and was going to fill it in after sitting for year and a half. I spent so much time and money on pumps filters lights and liners , I had to try one more liner I bought the 20 x 25 and it is great. A sturdier liner that I know my pond will look.great for Christmas. Thank you for selling a product that is described on line. I have never written a review but I'm so happy with your company I had to.

Thick liner

I got this product for a coi pond we are building. Although, the package was ruined to no fault of the merchant, it was still intact. As a courtesy to us, Amazing Pond also sent us a repair kit as a good faith offer due to UPS negligence. Thank you for rectifying what could have been a bad situation!!!! BTW the liner is thick and durable!
