I'm saying soaker, just so he doesn't get left out. Not a chance anyone ever actually uses it.

I used to use it to water bigger trees when you just leave it on the ground at the base of the tree for like 15 mins. 

Saves you from having to at least screw the nozzle on and off but pretty much the same as just using a hose.
