Like all Lezyne pumps this one is very well made. When stowed the pump is well sealed from road dirt. it is capable of getting a tire up to or near full pressure much more quickly and easily than the typical pocket size frame pump. The pump itself gets five stars. My only complaint is the provided bottle mount mounting clip. With the pump on my steel frame with the clip on the seat tube the base of the pump sits nicely on the bottom bracket shell. I'm not sure it would work as well on a carbon frame with a sculpted bottom bracket. I think a more secure mounting bracket would be a definite improvement.
GREAT LITTLE PUMP has the power to pump my 80, pounds of pressure tires. I had to put a little RED tape on the gauge SO I KNOW WHEN TO STOP PUMPING because the numbers are small and hard to see in the low light BUT NO BIGGIE!!
This is a machined precision piece of equipment, that will fill your tires up. Best road/trail pump on the market. THave one for my 29er and my Road bike, Highly recommend.
