I've had it less than 2 months and I don't know why I waited so long to buy it. Trying to find the right bolt or nut is much easier. Really helps me as I've found that most of my gauges and such are metric and not SAE. So I quickly realize that instead of trying to find an SAE nut in my trash cans that will never fit, I need to run to the store. An additional benefit is that I now "learnβ measurements by eye. It's like looking at a hexagon and just knowing how big it is. Love it.
