Looks the part now it's in the pond and it's holding the water which is obviously a bonus. Easy to fit and cut with ordinary household scissors and folds easily for awkward areas like corners.Unless I'm reading the terms and conditions of the 25 year guarantee wrong, it only covers it for degradation from sunlight, not leakage for any other reason. Fair enough if you puncture it with something sharp but not much use if it leaks for any other reason, e.g. imperfections in the product itself. Don't know how you'd fare then. That aside, it seems good value for the price. Time will tell.Update --12 months on and it's leaking like a sieve. I will now have to drain the pond, no easy feat as it's established and full of wild life and plants but no other choice. This time I'm going to invest in a heavy duty liner and hope I don't have the same problem in another twelve months time. Best advice would be to save your money and don't buy this one. ### ⭐⭐⭐⭐ 4.0 out of 5 stars not bad for money *by A***R on Reviewed in the United Kingdom on 5 April 2015* Very disapointed with first liner as it was fitted and leaked. It had clear factory damage. However ive given this four stars because of the fantastic customer service. I was sent a new liner free of charge with no fuss. Now this liner is fitted its great, a 2000 ltr pond lined for under 30 pounds cant argue for that. Just remember not to scrape it when cleaning it out or stand on it and I see no reason why this wont last for years. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Summers COME!! *by M***N on Reviewed in the United Kingdom on 18 March 2013* Yep, we all want a beautiful pond right??? well I used very cheap damp proof liner for years which are great at like £10each but I couldn't get the size. this one was a little tougher to fit because its thicker.. but the heron ain't popped a hole in it yet either!! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/48954641-flexiliner-pond-liner-4x4m-with-25yr-guarantee](https://www.desertcart.pl/products/48954641-flexiliner-pond-liner-4x4m-with-25yr-guarantee) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-12*
