Unlike the lever operated pump heads, this one has a thread on head that's easy to righty tighty lefty loosey resulting in no bent stems and when it's on, you know it's securely on. No leaky pumping. Also, the amount of escaping air when you loosen to remove is much less than with the lever operated type. The only thing I'm not sure about is the scratchy sound it makes on the plunge.
This pump has the build quality that has become a given with Lezyne products. Two things should be considered before getting one, though. 1.) The screw-on coupling is large. It is not well suited to bikes where there is limited clearance between the spokes such as small-wheeled folders and small children's bikes. 2.) you have to anticipate losing up to 5 lbs. of pressure as you thread the chuck off of a valve. My only other complaint would be the extremely limited cryptic pictorial instructions contained only on a small tag zip-tied to the pump handle.
This is a really nice pump. It fits both schrader and presta valves so I can use it on either my road or mountain bikes. The head screws easily on to the stem so you dont loose tire pressure when conecting or disconecting. It has a very stable base and reliable place to store the head so you dont step on it. And, the price is reasonable and it comes in colors.
The only thing I might fault is that, while large, the face of the guage is silver with black markings and can be a bit difficult to read in dim light.
All pumps are still in operation, just needed one to leave in the car and one in the garage. Two others the kids have at their house. Great gear with no problems, and if you do you can take it apart and fix it yourself with parts from Lezyne. Great tech support that you can understand and quality materials.
I really like how Lezyne interfaces with the tire. Rather than using a leaver, Lezyne uses a threaded chuck. This is not only a better interface for inflating, but it also doesn't feel like you are going to rip the valve stem off when you remove it.
This pump is a huge upgrade from the inexpensive floor pump I have used for many years. Fairly priced, excellent quality materials and finish. Works equally well on both types of tire valves. Higher PSI�s take a few more strokes than you might think, but you�ll get there! Love the gauge too.
