  • So far its been great
Size: 20 x 30 FT
After a year of use, this liner has proven its durability by consistently holding water, even enduring freezing temperatures and occasional foot traffic. Initially inexperienced, I underestimated the importance of proper landscaping, leading to some issues with heavy clay soil washing in. However, after a thorough cleaning and reinstallation, I'm impressed by its resilience. I couldn't get all the muck out by hand to remove the liner and what was left was extremelyheavy, so what I did was tie a corner to a tow line on my truck and I pulled the whole thing out. Honestly, I expected to destroy this liner in the process, but it survived completely unscathed. I'm currently in process of enhancing its appearance with gravel and rocks for a more natural look. While I've been cautious with heavier rocks and jagged edges, it's necessary for the desired look. Contrary to some negative reviews, my experience has been positive, though it's worth noting it may not be suitable for a natural swimming pool. I'll provide updates if anything changes. ... show more

  • Never to buy this product…
Size: 20 x 30 FT
I disliked this product coz the quality is very bad. It ripped when it was installed. I have to buy another one. It’s cheaper n second to the top of the line but the quality were not good .It’s a waste of money.

  • Not Best for Narrow Deep Pond
Size: 16.5 x 26.5 FT
Arrived fast and relatively easy to instal but not ideal for a narrow, deep pond. We had to order a large size to accommodate the depth so have tons of extra material to cut and stuff. So far it's holding up well but the algae loves it so trying to get more plants to cover the sides better.

  • Excellent liner!!
Size: 16.5 x 26.5 FT
Spend days trying to decide on a liner so happy i decided on this one!! The price was great for the size and it is Super durable and easy to work with i originally wanted a thicker mil but read they were to hard to shape. I exspect this one to last the material is just the right thickness and the way its woven makes it durable. my turtles and goldfish are super happy to finally have thier outdoor pond😁😁 ... show more

  • Best value for inexpensive liner.
Size: 16.5 x 26.5 FT
Its best value for size if you need a very large one. Not super thick.

  • Best for price
Size: 16.5 x 26.5 FT
The media could not be loaded. So far so good. I think I made the right decision on the type of liner. This was relatively easy to work with and no leaks now that I’m finished. Time will tell. I hope it holds up. I was able to double line it since my pond is only about 10x4.
