I carried one of those tubolitos around for a couple of years, when I finally had to use it, it lasted about 1/2 the way back to the car, and I ended up having to carry my bike for the last 3 miles. The weird detachable valve stem was the weak point, it somehow popped off as I was riding and I couldn't find it. Very grumpy.
