We inherited one of these garden hose attachments from the in-laws, and it works so well I bought a damaged one at a thrift store and repaired it just to have a spare around for the trees and roses. Heck, I didn't even know what it was called. I searched under "soaker head", "diffuser", etc. with no luck. Totally by accident I finally stumbled upon it. So, I'm wondering if you guys (and gals) know what they are, or am I just ignorant?
