What I like it's sturdy. The air inflates into the tire almost silently when in standard pump mode which almost made me believe it wasn't working, but it was. The digital readout is clear and accurate. The hose is long and it has plenty of distance so you're not crammed up against the wheel. I pump the chamber up to 120 lbs and it delivers 60psi in a whoosh into my 700-25m tires. This is flawless performance. I had no trouble at all operating the lever to release the compression chamber. No complaints.
What I don't like it's big, I mean big for a pump. Probably all these tubeless tire inflators are, I don't know. And it's expensive. But all in all, if it works every time, which this promises to do, it's a sound investment. I have other Lezyine products which work flawlessly, which is why I went with this one over a Topeak or the equivalent.
