  • Good product at a reasonable price.
Size: 7FT*10FT
The liner is as advertised in quality and thickness. We purchased two for our pond to ensure protection from leaks (and because I simply don't ever want to redo the pond of I can help it, haha). The liner laid easily once warm. Upon unfolding we simply let it lay in the pond area for 10 minutes to relax in the sun, after-which it was very easy to fold and work with. The liner did not have any noxious odors like some alternatives have had, nor was there any oil or residue on the waters surface upon filling it. I feel it's a great product and a good price. ... show more

  • Working perfectly!
Great for small ponds! Thick enough so it won’t puncture.

  • It’s a lifesaver!
Size: 7FT*10FT
My plastic pond part broke. I was devastated to see my water slowly leak. I ordered this. Installed it over the old pond insert. It works great. It’s pretty thick. Thickness is good but also makes it hard to do some bends. I’d rather have it have trouble doing bends vs thin and break.

  • Too rigid, no flexibility
Size: 10FT*10FT
I purchased this to replace a 12 year old liner which finally gave up the ghost and I am very disappointed so far. The material is rigid and difficult to work with, even after allowing it to sit in the Arizona sun for several hours. There is no flexibility whatsoever and with the creases I'm seeing already, I'm not sure if it can go the night without leaking. I am hoping it does because I don't want to have to replace it. If there are no leaks, I will update this review. Update: It's been over a week and the liner does not appear to be leaking but I stand with my initial review. To rigid, not flexible and difficult to work with. ... show more

  • Great pond liner
Size: 7FT*10FT
Nice and thick liner but also moldable

  • Ripped as soon as rocks were added to pond
Unfortunately our experience with this pond liner was not as good as others. It ripped immediately while adding rocks to the pond. Might work if you’re not adding rocks to the bottom. Most rips occurred where the products “folds” were. But other spots ripped too. Also not very flexible, more like a hard plastic than a malleable substance like other liners we have used. ... show more

  • Great deal, exactly as offered.
This is an outstanding deal, much much cheaper than any other product that I saw. I've been jumping in and out of my ponds trying carefully at first and then just hopping in as I've been installing it and it's held up really fantastic. The pond base that I've set this over has small pea sized stones and rough dirt, it is not smooth and the liner just really held up well. The thickness 20 ml is half - 5 compared to the standard 45 ml. It is difficult to work with because of the nature the material (not unique to this product) and requires a decent amount of effort to get it placed, of course dependent on the shape of your pond. But compared to a 45 mil this is really easy to work with. I would recommend a second person to HELP. Also depending on your base that you're placing it on, especially if the base is smooth or soft dirt, I think this is more than sufficient versus a 45 mil. if you have a lot of sharp rocks in the pond, you may want to think about it a little bit but really the price is incredible versus other options. ... show more
