the US products wand is a joke, how long will it last after being thrown into trucks by techs, what supports the valve system?? plastic?? a wand has to be a S design or its pretty much an outdated design, the US products wand does have a mid S, but the vac head is too high profile, the best wand design EVER made is the
prochem Ti and quad jet wands end of story. these wands will last at least the life of the truckmount, the valve assembly is bulletproof, it is ergonomically designed to not hurt your back, all other wands are junk in comparison
