I've bought this liner from Pond Keeper's before and found the quality and usability good. It's guaranteed to last years and from what I can judge, I don't doubt it will see me out.

I have used this product before and I have not had any problems in the past. The liner has a life span of 15 years but I tend to renew mine every five or so due to a blanket weed problem. So this is purchase number three and I am still very happy. Itís easy to lay and cut to the shape and size required.
