Thick and lasted a year throughout. Weathering finally won out after a year, however, and it gained a slow leak. Decent for the price point, though.

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.

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.

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.

DOES NOT STRETCH! This is NOT a rubber liner. You have to fold it, as you fill it. Nice and tough, easy enough to install if you pay attention as you go. Large, especially for the money! Love it!!

I originally left a positive review after ordering this on July 3rd and this is a update on Sept. 18th with a negative review. I ordered the 10x10 pond liner. I also installed a automatic float in the pond that will keep the pond topped off. The float was dripping 2 drops per second and I was puzzled as to why. In other words it was leaking constantly non stop. I took the pond apart and pulled the liner out and it had dozens of pin holes and leaking badly. I didn't have anything sharp in the hole just dirt. I purchased another liner and installed it today. The return window closed for the leaky one. I strongly advise against buying.

I wanted a pond but buying those tubs is very expensive. I ordered this and crossed my fingers hoping it would do the trick. It works perfectly. Material is very very thick. We put big very rough rocks and gravel all over it have multiple fish and a fountain and it hasn’t snagged or ripped at all. We have now had this pond for over 6 months and still no issues. If I ever build another one I will 100% be using this stuff!
