That great to know the v4 is quality and also that Tony Dang gets royalty as hes probably not able to work .
Whats cheap on the earlier ones though? i have a
v3 perhaps ... the one with the jets integrated into the head before shear angle became a thing .
But its not a rocket ship for thing to go wrong ... the head is forged alloy ... the non drip jets are standard jets ... the swivel ... never broke , greases the bearing now and then ( i prefer it locked anyway ) so thats the head ... the pipe is titanium pipe ... the hose is a rated hose ... the valve is branded ...
thats pretty much it ... not much be be cheap or fail .
