Yes they are a get you home solution and the hole needs plugging professionally. But, saying that, I have known people use these and it’s held up for the rest of the life of the tyre.:w00t:
It depends how stupid trusting you are;)
did the kit come with a case to keep it all together under the seat?
No, just plastic with cardboard backing. You could stick it in a plastic bag, or fold it all up in a rag or something ?
ok cheers, sounds good for the price
Let’s hope you never have to use it 
Has anyone used the tyre plugger professional kit, you get a green gun which forces the rubber mushroom shaped plug into the tyre?
Could you let me know if they are any good, also if there’s a video of how to use one?
