  • Great quality, but difficult to maneuver
Size: 20 Mil - 4 x 7ft
Material is very durable, however it is quite difficult to get into a specific position. Bought for the bottom of my chameleon cage and trying to get it to fit into the cage was close to infuriating. However, once the corners were cut down and folded a bit it worked like a charm. No leaks either!!

  • Might not work for me, but exactly as described
Size: 20 Mil - 4 x 7ft
I plan on using this to line a whisky barrel to make into a small container pond. While the product is exactly as described it might not work for my project. The material is a diff type of plastic than the normal sheet plastic you get at the hardware store, and a lot stiffer. Not sure I’ll be able to get it to fit the tighter corners of my barrel. Also should have gotten a slightly larger size. 5’ would have been nice for the barrel. I’d likely love it for a more traditional pond. Seems pretty tough! Again, product is as described. Just thought I’d leave this review for others with similar plans. ... show more

  • HOPE IT LASTS AS LONG AS THE LAST ONE
Did the job at a reasonable cost. wish the material was more pliable as it was difficult to form it into the overflow barrel used as the filtration system.

  • Works in my waterfall!
Size: 20 Mil - 4 x 7ft
Seemed a little stiff at first but once I opened it all up it was quite flexible and fit nicely in my waterfall area. Works great to fix the leaking area in the base water collection area of waterfall.

  • Great quality for the money
Size: 20 Mil - 4 x 7ft
I bought this to line a small water feature in our back yard and it has been holding up great with no leaks, even with heavy rocks piled onto it.

  • fine on flattish surfaces, does not work well turning up vertical walls
Size: 20 Mil - 10 x 13ft
I used this as a liner for an oval-shaped cement pond that was leaking. The base is about 6'X8', with walls about 4' high. I thought the water pressure would make the liner adhere to the walls, but no. The liner is thick, and it creased deeply as it rose from the flat bottom along the walls. Then, even with me scrambling around to hold it in place against the sides as the water filled, the sides of the liner folded over and let the water escape. I wrote to the company which suggested that I anchor the liner with stones. I had already used bricks plentifully, but to make it work in my pond, I'd pretty much have to completely brick the liner in. When I told the rep that, they fell silent. So, the liner is useless for the purpose to which I applied it. It's a good quality and was easy to work with, but if your pond has walls that rise at a 90 degree angle from the base, as mine does, this is probably not the product for you. ... show more

  • Extra Thick and Sturdy
Size: 20 Mil - 4 x 7ft
Excellent purchase. I only needed a small piece of liner and this fit perfectly. It is very thick and sturdy while being pliable. I recommend buying for a smaller project.
