Solid, reliable connect and disconnect even when blasting 100 psi all at once to seat tubeless tires beads.
Pressure gauge is nice and big too. Only drawback is that the pump is too tall and huge for my daughter to use. So I still have to keep another floor pump around for when she wants to help.
Looking back, I'd probably only buy it if you need the tubeless functionality, though. The head makes the pump, apparently, and it's easy to find a different head or even use their metal head kit on a different pump.
I just got this and the new valve head has a shorter tube (annoying but bearable) but also has the pump end adapter thing already inserted in the tube and the pump also already has one in place, after my having pulled the old plastic-head tube off it. Neither seem to be removeable by a human. How did you deal with that, may I ask?
