After using the TEZONG Pond Liner for my backyard koi pond, I have some thoughts to share. First off, the size (20x25ft) is fantastic for larger projects. I used it to line a waterfall stream leading into my pond, and the width ensured no leaks at the sides. The 28-mil thickness held up well under decorative rocks, which was a relief.

One of the standout features is its flexibility. It was easy to trim and shape to fit the curves of my water feature. The material feels durable and UV-resistant, which is crucial for outdoor use. I didn’t notice any tears or punctures during installation, even when maneuvering around sharp edges.

However, not all experiences are positive. Some users reported leaks, with one mentioning the liner 'leaked like a sieve.' In my case, I didn’t face this issue, but it’s worth noting that proper underlayment (like sand or a protective layer) might be essential to prevent problems. The stiffness of the material was a minor inconvenience during installation, but it didn’t affect performance.

The liner’s versatility is a big plus. It works for ponds, waterfalls, streams, and even aquaculture. For DIY enthusiasts like me, it’s a cost-effective solution compared to pricier alternatives. That said, if you’re looking for something more heavy-duty or guaranteed leak-proof, you might want to explore other options.

Overall, the TEZONG Pond Liner is a solid choice for most backyard water features, but your mileage may vary depending on installation and environmental factors.
