Any consensus on what's the best brand of sprinkler heads? I've

At $Dayjob, I believe a sprinkler system was installed in 1999, and it
had all Hunter sprinkler heads (about 3 or 4 dozen of them).

About a dozen of them have been replaced over the past 2 years. Not
because they don't pop up (they always pop up). They stop rotating
through their pre-set pattern (they stop at one end of their rotation
sweep and fail to reverse direction). For smaller areas, they've been
replaced with heads that don't turn.
