Thought I had a nail in my tire the other day. Went over to Ted Weins and the gentleman ( can't remember his name) pulled out a short little bugger. He tested the tire and said that it was so short it didn't damage the tire at all. I asked him what the charge was, and he said nothing. I was shocked. He told me that if it was a true puncture he would seal it, but nothing needed to be done here. I like this sort of honesty. I will definitely use them again for my auto problems.
