I purchased this pump approx 3 months ago because of the screw on head. My older Joe Blow pump was the push onto the valve type head and seemed to contribute to bent or broken presta valve heads when pumping up my road bike tires. This new lezyne pump has eliminated the problem of bent or broken off presta valve heads. I pump my tires atleast once a week. I am pleased with the pump..the digital accuracy is nice too...but the primary feature i wanted and like is the screw on head!
this is a great pump, the ABS2 takes a little getting used to, but better then the older style of screw on valve and better then all the other mfg's lever valves. Very efficient pumping although I wish it had the wood handle of my older Lezyne pump
