My Lezyne steel floor pump is about six months out of warranty, but the fill nozzle cracked and the gauge quit working, so I contacted Customer Service who said they would "totally take care" of me by immediately shipping me replacement parts at no charge. I bought the pump mainly because everyone said the Lezyne makes the best pumps and has stellar customer service. While the first statement might be suspect, given my experience, the second certainly appears to be true.
Other than these two problems, I like the pump a lot. I especially like the screw-in fill nozzle much better than all those clamp-on arrangements you find on other pumps. With reasonably deep dish wheels and short tube stems, getting the clamp-ons to work can be a hit-or-miss affair. Plus, I've torn tubes trying to disengage the fill clamp from the stem on my first pump, a cheap-aze Park.
