I have had an issue with the Lezyne unscrewing valve cores on inner tubes, but I do seem to have a bad batch of Continental inner tubes where the cores aren’t screwed in properly (just unscrewing the dust cap has taken them out). I’ve no idea how it’d be with tubeless.
Equally though I’ve had problems with standard style pumps breaking free during pumping and bending the frail ends of Presta values; IMHO the flexible tube and screw on head is much better. All in all the Lezyne is by far the best pump I’ve used (although it is the only mini-track pump style one I’ve had).
Build quality is great and I think that the heads and hoses are available as aftermarket spares. It is a little pricey for a pump but not overly so compared to other mini-track pump styles; available with or without a gauge.
