Got my first ever puncture :(

[darrsi]

Tyre changers hate that stuff as it makes a right mess of their kit when changing your rubber. Just make sure you tell them it's in there!

Not heard many reports on whether it's any good or not though.

Over the years i've probably used it in 3 of my tyres, as i said above if your tyre's past half way, but still has plenty of mileage left and you have an irritating slow leak, then it's very useful gear.
My bike is mainly used for commuting as well so it makes even more sense to use it if needs be.
I'd imagine it could really get you out of shit if you were touring and in the middle of nowhere as well.
I wouldn't use it all the time though as i have an RAC card, and if a tyre has a chance of being internally mushroom plugged then that's the way to go.
