  • Awesome liner
Size: 7-Foot by 10-Foot
The liner was very thick and sturdy to be so inexpensive!! The profit feels also like rubber It does mold easier if it is out in the heat .i will order again for my next project.

  • Still holding water
Size: 10-Foot by 13-Foot
I built a goldfish pond about 2 years ago. Liner is still working. You need warm weather to install it. It's a little stiff.

  • Depends on your application
Size: 15 ft x 20 ft
I bought a home that had an old unused pond that I needed to get back into operation. The home was 22 years old and I am sure the Michelin liner was original. However, past owners had butchered the liner when adding a new pond skimmer and it leaked so much it was abandoned. I bought this liner as it is certainly much cheaper than the Michelin liners and I laid it on top of the old Michelin liner. This liner is thick, it is strong, but it is also fairly stiff. It was sunny and hot when I installed it as other reviews said that helped keep it more pliable. A light breeze was blowing when I laid it out and as the breeze would blow the edges over, I would have to go straighten it out again. But when I would pull the creases out it would still be stiff enough that it would leave a crease in the tarp. (See pictures) I had to be so very careful placing the rocks back on the tarp as I was paranoid that it will damage the tarp. I have filled it with water, and after 2 weeks there is no sign of leaks so far. I don't think the product description is false or deceiving, but I do believe this tarp is not for every application. After working with this liner and the Michelin liner, there is a huge difference in the material. The Michelin is basically the same material as a tire innertube. Hence the maker...Michelin. It is strong and pliable. It will last 20+ years. I am sure I will be replacing this liner again in about 5 years do to the bending I needed to do for my application. If you are doing a simple shape in your application, this tarp will do the job and probably last 10 years. In hindsight I wished I would have just forked out the $400aprox for a rubber liner so as to not do this job again in my lifetime. I hope this review helps in your decision. ... show more

  • It's thick
Size: 7-Foot by 10-Foot
This is the best buy I've found for a liner this durable. In reading many of the reviews I saw that many people complained that it was stiff and hard to work with. I'm not sure what those people expected but if a PVC type material is thick, it's going to be a little stiff, period. I rolled it out in the sun and let it warm up and found it easy to work with. And did I mention that it's thick, and durable, and strong? ... show more

  • Better luck with a tarp.
Size: 7-Foot by 10-Foot
Way too thin for use over anything but the softest soil. I have had to tear apart and rebuild my small water feature 4 times and I still have leaks. This liner is so thin any sort of abrasion will cause a pin hole and then you are sol. Even with a thick weedblock as a barrier underneath and on top - there is leaks everywhere I turn and I am having to refill the reservoir after less than 24 hours. So going to rip this out and buy something thicker/better quality. ... show more

  • Hard to use
Size: 7-Foot by 10-Foot
I wanted a smallish frog pond and thought I could get by with this really inexpensive liner. It is very stiff and doesn’t want to bend. It was really hard to fold at corners. By the time I was finished, it had a leak about 5. Inches from the top.I’m using it for something else or I would request a refund. It will work nicely for my living roof project. ... show more
