Let me start by saying this pump feels like it could survive a zombie apocalypse. The anodized aluminum barrel and steel base give it a tank-like build quality. When I first unboxed it, the weight (4.3 lbs) immediately signaled this wasn't your average bike pump.

The dual-function design is where this pump shines. The primary pump works flawlessly for regular inflation - I've used it on both Schrader and Presta valves without issues (though some users report Presta valve struggles). The SmartHead DX3 chuck engages quickly, though the air release button requires firm pressure.

Where this pump really earns its keep is tubeless tire installation. The booster chamber is a game-changer. I successfully seated three different tubeless setups, though like some reviewers noted, very supple tires can be stubborn. Pro tip: inflate to max 160psi before releasing the air blast for best results.

The gauge is beautifully large and readable - no squinting required. However, I did notice the same quirk others mentioned: after using the booster chamber, residual air remains in the line requiring additional pumps to reach target pressure.

At $160+, this is an investment. But considering my 8-year-old Joe Blow Sport still works perfectly, I'm betting on similar longevity here. Just be aware you might need to buy their $30 alternate fill head if you primarily use Presta valves.

Bottom line: If you're serious about cycling and especially tubeless setups, this is one of the best mechanical options short of a compressor. Just manage your expectations about the Presta valve performance.
