Light weight and easy to handle and cut. With a forty year life expectancy it appears to be very tough.

It was much thinner and more flexible than the pond liner I had used before, so easy to lay. Only time will tell how good it is /long it lasts,but no problems yet.

I used the online pond liner calculator and there was enough underlay to do my pond three times and almost double the amount of liner I needed - however, it might have been me who mis-measured, rather have too much than not enough.

If it lasts as long as promised, I'd give 5 stars. It would have been helpful to indicate how the liner folds were organised.
