Recently used this pump on two, week long, bike tours with tubeless Panaracer 32s and presta valves, at 50 psi. It's simple to use, the gauge is easy to read, and it's easy to switch between high volume/high pressure. My favorite feature is that it clamps (does not thread) onto the valve stem. No more inadvertently unthreading the valve core when removing the pump.
Since I am running 2.2 Conti Trail Kings, I primarily use 16gr CO2, but this is a good pump to adjust pressures and refill if you have a tire burp.
I already had to use it on my road bike (filled to 100psi) and twice on my dirt dawg. It is solidly built and the gauge seems accurate. I'm glad I purchased this, I only wish the price wasn't as steep. I definitely see this lasting for years to come.
