David L.wrote a review of Lezyne Gauge Drive HP Pump on December 10, 2017
Familiarity: I've used it once or twice and have initial impressions
Cheap plastic end cap filled one tube then failed, the threads pulled out where the gauge hose (the reason I bought this) threads into pump body. Called Lezyne customer service, they sent me a METAL replacement, and instructions to replace. OK. Plastic end glued in with some super glue of some kind, heated with butane heat torch to loosen, cut a slot in the plastic cap like they said and tried to remove. It was going to break the hack saw blade, switch to a stiff scraper. Re-heated several times, finally grabbed pump body with pipe wrench in desperation, still, plastic cap would not budge. Seriously risking physical injury at this point. So, may work with metal cap, but don't risk it!! Nothing worse than a flat, oh, except when you spend fifty bucks on a POS pump and end up walking in your cleats anyway.
