Having not received any responses, I ordered one. It seems to do the trick for the purpose I want - inflate tires for an emergency flat, and keep the pump in my under-seat bag. Using the high vol setting, I got the tire to about 41 psi, after a lot of pumping. The pump is very hard to use on the high vol setting at that pressure. I then switched to high pressure setting, and got the tire to about 46 psi. by then I was tired. That is enough pressure to get back. the blackburn shorty is probably better, but I have not tried it. It is also about 1/2 longer, 2x the price, and would not fit in my seat bag.
