17 weeks and only one flat tire-kinda. I was out on a ride and something wasn't right. I got off and noticed the tire was low-not flat. Then I found a thorn right in the middle of the tire. When I pulled it out it made a hissing noise, and then my fingers got wet. That was the Slime doing it's thing. I had enough air in the tire to get the last two miles home-filled it up-that was five weeks ago and I'm still riding.
I guess you could say I'm sold.
