Title: Great concept, but one size does not fit all
Review: Unfortunately I had to purchase 24 of these things and I only needed 4. They said it fits various sprinkler heads, but it didn't fit mine. I am sending them back, all 24 of them. They're huge in diameter, so if you order them, make sure you're aware of the size and quantities you'll be receiving.
