it is actually very easy to use, even by hand. i have used both methods being here in cincinnati, and this tool is great for a quick fix at the track if needed. OSRockets procedure is a little more advanced, but can not be done at the track. i dont know how many guys have been able to continue racing because of having this tool at the track, and continue racing for many more weeks and months.

Why do you need to pinch your sleeve at the track!!!???!!!

You normally have plenty of warning that your engine is on it way out....not like 1 tank mega compression and the next hissing air!!??

Hiiiiiiiiiiiiiiiissssssssssssssssssssss!!!
