I completed my garden pond yesterday. I'm hopeful that the 40 year guarantee on the liner holds true as I'm too old to re-do it. Frogs love it.

Hard wearing - although as I've just put it down I can't comment on the 25 year claim. It feels thick and was easy to place and was easy to cut to shape. I am happy with the product.
