  • Good durability for the price
Size: 15ft x 20ft-15mil
Heavy duty enough for regular use. Not for unprepared surfaces. Cuts with some difficulty (which is a plus, not a minus). Would order again.

  • Heavy duty but easy to work with
Size: 15ft x 20ft-15mil
I used for a 13ft x 7ft pond, approximately 2.5ft deep. This liner is heavy duty yet easy to work with. Recommend highly. Easy to cut with a good pair of scissors.

  • QITUO Pond Liner,15 Mil HPDE
Size: 15ft x 20ft-15mil
I’ve been using this for about a year with turtles and koi, and it’s holding up reasonably well. I wouldn’t recommend it for long-term use, but it’s fair for the price. I’m treating it as a temporary solution before upgrading to a higher-quality liner.

  • Pond liner
Size: 15ft x 20ft-15mil
So far it is holding up. It was alot bigger than I thought; which isnt a negative. I just had to cut more of it to fit my needs. Better measuring on my part could have prevented the waste.
