Great product. Very thick and strong. Only little moan I have, is that there were white lines and patches, where the black colouring hadn't covered properly. This will no doubt, turn green over time, like the rest of the liner will.
I would also say, the free underlay, although quite strong, is extremely thin ... more like weed guard for under pebbles/slate. I ended up buying some polyester wadding, to use as underlay instead.

Liner seems extremely good quality. This was recommended to me by my neighbour, who has a large pond. Mine is small but Iím very pleased so far.
