I have not had any problems with it at all. Maybe they make them differently now?
I just went and read a few reviews. Seems the first few left it out in freezing temps, causing internal parts to freeze and break.
I must say, I do not use this nozzle for everything. I use it for spraying daylilies.
It does not have an "instant" on/off, you have to twist it to turn off. I prefer, for everyday hose use, to be able to turn the water on and off by pulling a trigger, or squeeze-type handle. Most of the time, I use a simple on/off hose end, with a Dramm Water Wand connected.
I don't leave my hoses out in freezing weather. They are drained and stored in the garage.
