This sprinkler is very particular about the water pressure coming through the hose.  Too much and it leaks all over; not enough and it doesn't do anything at all.  I like the sprinkler once I figure out how far to turn the faucet on.  It does a great job on my square garden.  The adjustments work great for different shapes.  Using the square shape does not cause any overspray in my garden.  It is very lightweight which is nice but concerning.  Lightweight sprinklers have not lasted long historically for me.  I have only had this for a few weeks but I am happy with it so far.
