As practical as they say.

On top of that cheap, far less than retail.
We have several garden hoses (normal, striated etc) in the greenhouse and I assure you that it is very, very far but really the most practical, easy to use, lightweight, fits very easily.

The less I say, the sprinkler head seems cheap (but no problems with), and the explanations are very light.
You must adjust along well supplied with rubber (4 if I remember correctly) so that there was no more discharge from the mouthpiece or head and remember to shut off the water before otherwise is the shower.
Avoid leaving full of water once finished using it, especially for the winter, or outside in the summer and everything should be fine.
