These sprinkler heads save you a lot of watering. I can turn on my system and run it for 5 minutes and not get the same results with my hose in much more time. I put this together with a splitter on my hose outlet on the house and some rainbird tubing. My lawn looks pristine and with minimal work. Digging these in only requires a little work with minimal dirt removal. Anyone can do it with ease. Prior to installing this I had the saddest lawn on the block but now it's the best!
