Most of the hose nozzles I've had over the years failed in one way or another. The fancier they are, the more likely to **** out. Plastic ones crack, cheap zinc/pot metal ones corrode furiously. The ones that have been around the longest are the simple brass twist nozzles. I have a few that are always there to count on, periodically I take them apart, chuck them in the blast cabinet and clean them, then replace the o-ring and washer, they are as good as new. I have a couple "selectable" nozzles I use and bring into the house when done. Even doing this amount of care the complex ones often die in a few years.
