Two months, but it has been a slow couple of months. I do like how solidly they attach to the solution hose and the qd. I went from a ball valve with a large handle. While it would occasionally get caught on my pants pocket when wanding the handle was easy to grab and turn. The smaller valve on valves the size of the Jvalve (there I just re-named it) took some getting used to but only a day or so.
If you didn't send me enough to put on everything I would order some. I can see these valves lasting me an o/o about 9 months to even a year even tho I drag. I'm not bragging about dragging but I am confessing to it and I like having a valve that can take the abuse and not catch on things it's dragged around i.e. lawn and garden decorations (never walls, never drag it around the corner of a wall).
