I can see the advantage there, it coils back in the box easily.
Here is another one cheaper.
For my spray nozzle, mine is fixed, a sweeper nozzle.
To turn it on and off, I have a rotary plastic valve with a quick disconnect fitting also bought from Amazon.
It is pretty decent actually, still working since 2014 and in salt water.
For this type usage, all plastic is great. All the other handle type nozzles fail in a few months. Even cheap plastic spray handles have a steel spring.
