I have only used the Slime over the years, and I just installed this on one tube, so can’t say if it’s effective or not. However, the packaging stinks if you plan to use it with a Schrader valve inner tube. The clear plastic tube used for installation is kinked in the bottle top's outer ring, which leaves two deep kinks in the tube that you cannot work out. I even used a heat gun that is used for automotive work to try to heat up the kinks and allow me to use the rest of the bottle. Forget it! I ended up leaving about 25% in the bottle and throwing the whole thing out. Back to Slime for me. Slime provides the tube taped under their bottle label which leaves it straight.
