Works fine to fill water balloons, which is what I wanted it for.  Quality is good and it's inexpensive so five stars.  Most people want this for its "jet" and it's fine for that too.  For filling water balloons though, I prefer the Nelson Brass Sweeper Nozzle 50161 on the end of a Gilmour 572TFR Commercial Insulated Grip Nozzle with Threaded Front, Red.  The lip on the Nelson nozzle helps hold the balloon and the spring loaded handle on the nozzle makes it easier to control the water flow.  The second system is a tad more convenient, but at more than twice the cost.
