Great product. Easy to form around curves. Installed 3 months ago and so far no leaks. In order to ensure success, any pond liner must be installed over a barrier membrane that will help prevent punctures from roots and other objects.
Got lost in shipping had to order another, company refunded me for the lost one. Other than that when we finally received it, it works like a champ! Hard to get all the wrinkles out, but does the job.
