Familiarity: I've used it several times
This was very helpful for seating tubeless tires without having an air compressor, but it took several tries with each tire. The culprit appears to be the chuck/nozzle, as it does not stay on well if it isn't threaded, and when threaded it seems to diminish the velocity of the air. Also worth noting is this is not a very good pump for everyday tire top-ups, as air seeps from tires back into the large chamber, meaning you need to pump tires almost from 0 everytime you want to top them up.
