Bests & Worsts Reviews from Amazon

I read mixed reviews about whether this was waterproof or not (needed to patch a couple intex above ground vinyl pool leaks). I tried it both inside and outside the (filled) pool, and neither worked in any way that could be called successful. We have some other tape that worked really well on the outside of the pool, so this is just an inferior product. I do not recommend using this for anything water-related. As soon as it was applied to the leak in the image, it bubbled up and leaked (the surrounding area was dried off first just to give it the best chance possible). As soon as the other tape was applied, there was no bubble at all and no leak. The funny part was when we tried to apply it on the inside underwater (the reason I bought this tape in the first place). We cut it into a circle and applied it as fast as possible, but it simply didn't stick except for the tiniest area. It lost all adhesion to the rest of the patch area and was completely ineffective at stopping the leak.
