Only used them when I had a massive shard of glass in my tyre and the little rubber strands I carry were to thin/small to use. The RAC chap came out with what you had and plugged my tyre. However, are they actually a permanent fix? I was under impression to permanently fix a tyre you need to use a big mushroom type thing from the inside. As surely anything you push in from outside could potentially pop out too? (but do correct me if I'm wrong here, I'm no expert).
