Very accurate PSI, great engagement on presta valve

Worst gauge on the planet. If I wanted something to just fill air I’d shop at Walmart. This product is worse, the gauge is useless. Customer service was like, yeah, that’s too bad. Wow ok, thanks for nothing! Don’t buy this

I love everything about this pump except it's inaccurate gauge. The gauge is highly inaccurate and therefore useless. The gauge on my pump is off by at least 5 pounds, resulting in the pump being useless to me and a total waste of my money.

I love how the pump functions and the gauge range would have been perfect, I loved the idea of having 0 to 40 psi over such a wide spread on the gauge, would have made it easy to read. But like another comment I saw, my gauge is probably off by about 15 psi or more. Hard to understand how such a big error can be allowed to pass through the system.

I didn't have an immediate need after I purchased it but was itching to test it out. I tried filling up my sports car's 335 wide tires and it freaking works! Takes about 2 pumps per psi or so. For a mountain bike this is gonna be amazing! I can't wait to knock tubeless beads into the side of my rim with over half a liter per pump without having to kick on a compressor!

Total bummer. It's a fancy pump and well built... except for the air pressure gauge. I used this frequently for about 60 days. It has smooth action and the nozzle is great. Doesn't leak any air. HOWEVER... the large fancy gauge is inaccurate. Real Pressure: 10 Psi -- Reading 1psi /// Real Pressure: 25 psi -- Reading 20 psi /// Real Pressure: 34 psi -- Reading 30 psi /// I bought this assuming the large gauge, which is easy to read, would tell accurate pressures. I check this with a two different detail gauges & another pump. This pump tells wrong air pressures.

Heavy but very nice. Hose is long and gauge seems to be within 2psi.

Great pump!!

Works great. My old tired eyes can read the gauge without any problem. Takes only a few pumps to get the tires up to pressure.

Setting up tubeless effortless. High volume let you easily add pressure to high volume MTB tires with only two or three strokes. Very sturdy construction. I am happy with my purchase.
