My first attempt at a sprinkler system. After some research, decided that hunter pgp ultra popups were the way to go. Found the best price for them here at the Sprinkler supply store, with a set of nozzles included for each sprinkler. Shipping was fast, ordered them on a weekend, had them in hand by the next weekend so I could get started. Two minor complaints. Hunter claims to have a nozzle chart on their site to help in determining which nozzle you want to use. I could not find this chart despite a considerable amount of time wasted searching their site. That's not the Sprinkler supply store's fault, but if they have access to it, and threw a copy in with each order that included hunter pop ups, that would be fantastic. Also, I was disappointed to find out that the adjusting tool, and the little plastic piece to hold the pop up open while you install the nozzle were NOT included with the sprinklers. This was an oversight on my part. But had the shopping cart page pointed out those two little accessories, and the fact that they were not included, I would have gladly paid for them to be added to my order. As it is, if I want them now, I have to pay 8 bucks in shipping to get 2 bucks worth of tools. Not gonna happen, so I made do without. So, 4 out of 5. If I need any more sprinkler stuff, I will be back.
