My neighbor decided to buy this DIY irrigation system off the internet. It hooks up to a spigot at his house and has I think 3 or 4 cheap looking bluebird heads. He old buried it about 4 inches and said its guaranteed not to freeze and bust. I told him I thought he had wasted $200.00 bucks but he put it in and it seems to work okay. Don't know how well it will work in 6 months but its his money to waste not mine.
