I thought this tape would be similar to the regular PTFE tape I can buy at my local hardware store; However, this material has a very different texture. It's much closer to the texture/feel of a Walmart grocery bag than the Teflon rubber strap I'm used to. So when I first got it and opened it up I was a bit skeptical and had low expectations. I'm pleasantly surprised that after a few weeks of use it seems to be doing its job - the spots I've used it on haven't leaked yet. We'll see how it stands the test of time, but for now I can't complain.
