Have had this pump installed on a touring/gravel rig for about 600 miles. Filthy conditions do not contaminate it, it attaches easily and reliably to tire valves, and inflates much more quickly than other (older) hand pumps I've used. Bringing a 400mm wide 700cc tire to 40psi from 10psi takes under a minute of pumping.
This is my second Lezyne pump, and this one seems to work just as good or better than the high pressure Lezyne pump I have for my road bike. I especially like the fact that it has a hose to attach to the valve. This prevents the rocking back-and-forth motion you get with a standard frame pump that doesn't have this feature. Nicely machined and fits well in its water-bottle mounted holder.
