Terrible product. Valve not easy to connect. Failed to seal small puncture
I appreciate that such items can be tricky to use at times. I can sympathise with you. Here is the film by Vittoria explaining how to use the Pit Stop product. When I read reviews at all the other retailers who sell this item it seems that some other customers have the same experience as yourself whilst others find it extremely effective. If you're not happy with the product and you still have your receipt then please return it to us for a replacement or an alternative item.

Sur internet il y a une très bonne démonstration sur le mode opératoire
