As others have said, this pump is a huge beast. To put things in perspective, I'm a runner who occasionally rides a MTB, and I'm replacing a 12 year old CyclePro pump, so this thing is impressive to me. It feels sturdy from solid base to long, flexible hose, to beefy head. It inflates much quicker then my old pump.
Forewarning to those with children, while the pump may be big and macho, be ready to battle your kids' bike/stroller/trailer/wagon wheels (or even that old wheel barrow) in order to fit the head onto the valve. I thought the old pump was a challenge, but it was a Tim the Toolman comedy sketch watching me try to get the head on my son's wheel! That's the reason I gave this four stars, rather then five.
