Used my pump several times, and let others borrow it when needed. Couldn't mount it using the included mount, as my crank would hit it. No problem, it's light enough that I didn't mind carrying it in my jersey pocket (I'm a Clydesdale+, so half a pound is no issue). I was using it a few weeks ago, and mid-use, the pump came apart and I cut my knuckle. I got it put back together and finished using it, but it began overheating from the friction of the two pieces rubbing together. Haven't used it since then.
The thing is tiny as it only weighs about 7 ounces and is 12” long. I tested it out by airing my front motorcycle tire (120/70-R19)
down from 36 to 32 psi. When screwing the chuck on I was surprised that it didn’t allow any air to escape. I didn’t actually count the strokes but I estimate it took about 30 to bring it back up to 36 psi. No air was lost when removing the chuck. It would take a while to go from flat to full pressure, but I think it will work great as a pressure maintenance tool and as a backup to my 12 volt compressor on road trips.
This pump is easy to use and fast. Well built.
