Nope, they're "DIG" brand from Home Depot, under $3 for a package of 3. Somebody edited my post above, because I posted closeups of the micro-sprinklers and the tubing as well as the back of the sprayer package that explains how you put them together. Guess maybe Admin thought I was plugging a brand of product. In actual fact, I like the other brand that Lowe's carries better for everything except those adjustable sprayers on a spike.
But I'm sure Mike can figure it out if he's interested.
Same thing happens for me with soaker hoses as with drippers - the water goes straight down through the sandy soil, and doesn't spread out enough to water big plants with wide root systems.
