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.

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.

Not quite as moldable as thinner layer, but thick so I won’t get any more leaks in my pond

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.

The media could not be loaded. The liner is thick but it’s very hard. It’s not like the typical liners that I’ve purchased in the past. Because of the material it’s made from, I have some concerns that it may dry rot fast. I will post an update to the review if this happens. It’s not easy to fold at all due to the hardness of the plastic and leaves wrinkles. I’ve attached a video so you can see the wrinkles and you can hear how loud the liner is when pressed on. I wasn’t impressed with it at all.

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

Very brittle. Installed carefully, filled and has a leak after 1 day. Have to keep filling the pond because I can't go through all the work of replacing it and have no idea where the hole is. I would not buy this brand again.

Used this for an outdoor pond, and it was exactly what we needed. Great price, good quality, waterproof, and easy to use.
