Also multi streams were supposed to be used to deliver water slowly, but the precip rate is high on the RB.
Like I said, JUNK. I have been trying to find a serious competitor to the Hunter MP but it has not come out yet. I would like to see the Toro multi's in action, I cannot speak to those yet.
Of course, they recommend using the R-VAN with a PRS-45 body.
But I have seen the RBRs spin ridiculously fast at high pressure. I have the RBRs in my front yard (rectangle, southern exposure) and MP Rotators in the back (shadier, north side of the house).
