Had this thing for some while now, never used it. Fella came along with a tyre this weekend with a huge nail in it. Thought I'd give it a try. Damn, it worked well. Pull out nail, ream hole a bit to clean it and rough the edges, shove needle tool in with length of sticky black string through it. Pull out, trim ends. Absolutely brilliant. Reckon you could do it in 30 secs or less if you got the tools out ready. Wouldn't do it on a Ferrari tyre sure, but off road with something like a nail, ridiculously good. Didn't even lose much air.
