This stuff is amazing. I have tried other solutions from big brands which was awful. I wasn’t to happy when I saw this stuff on shelf as I didn’t recognise it. But was stuck as had no other option, bike had a puncture and no were else to go. But wow!!! I squirted it in the tube pumped it up and it was sorted. Have done about 300 commuter miles since i pumped it up after using it and it is still holding strong. Since I bought this one, I have bought another two bottles and filled all the bikes in the house with this stuff. You won’t regret it. Best tenner you will spend.
