Ya we are sold on this thing. We can setup 4 timed watering zones very easily and if we need water out of the scheduled times just flip a valve and you have running water.
So we are almost complete getting our whole garden worked out and as a bonus we can do 2 garlic beds as well. Those are always a pain to manage.
Considering that a decent distribution node (like 1 hose to 4 outlets) is $30-40 the increased cost to $53 for this makes it a no brainer. You don't have to use the timer if you don't want to.
