Still Made In The Good Ol' Us Of A!

I use this thing as a keychain - it's made in the USA, it's a quality piece, and it works perfectly for checking the gaps on my spark plugs. On these Euro-spec cars it's handy to have the metric option on the back, too. 5 stars and $0.99 well-spent!

Some Guy

Nifty little gadget, perfect for the car enthusiast's key ring or if all you do all day is check gaps ;). I think I will use this more on my lawn mower than the Volvo, but hey: its there and its handy! Makes a cool gift too!
