I like the design,lol.
What beats me is why would anybody want to drag their socket though the dirt when reeling the hose in,I have my socket on the end of my hose and I never drag it though the dirt.I always bring the end (socket) back to the rig,undo the wand and lay the socket my the hose reel to keep it out of the dirt.I had rather buy several 1.50 parts as to buy several 3.50 parts to keep my cost down,the socket I have on the end has been there for a few years and I change o-rings maybe once every month or two,I do alot of changing wands when doing farm eqt.,I also do alot of twisting and turning of the wand,never have 0-ring problems,if my rigs is running so is my hotwater,cann't wash without it or I don't like to and usually want.What will get alot of o-rings is a pop-out which means you still have alittle psi in the hose when undoing the wand,I run a open gun so I do not have that problem.
