Commuters (and all cyclists) deal with flats. Fact of life. Saw this today thought I'd share.
It seems like this would have a limited value to me. I've had scores of flats over the years and in my experience a very small percentage of them have been from the types of puncture that this magic tool is designed to fix. I seldom find a nail or the offending sharp object sticking straight out of the tire (sure it has happened) But usually whatever causes it is not so obvious and I usually have to go searching for the tiny hole.
OK so it's not a thing for me, but I'm passing it along as a public service because I'm here to serve.
