I bought some of this tape when I needed to replace my bathroom faucet. This was my first time fiddling with teflon tape as an adult and I didn't realize how great it was until one day I used the cheap teflon tape that came with it to install the shower head. The thing was uncontrollable and the water was still splashing everywhere! So I came here and ordered more Mr. Gaskets (couldn't find another roll) and the second attempt to install the shower head went smoothly with no leaks. fantastic things.
