Just an observation on my Aquapro 75. Purchased early Spring 2007, so it is probably one of the newer problematic models. My battery was discharging right away after start up. I noticed some small arcing marks on the underside of the metal battery cover. The wiring harness spades that pushes onto the battery terminal were too close to the cover and direct shorting thus draining the battery. I insulated the terminals to prevent contact. Mine is set to go twice per day at 1 & 2 seconds. My solar panel is partially blocked by trees, I can now go all season without a manual recharge.
Shortly after the PB conference last year, I switched to AquaMax 600 from "Farm Pond Diet". When I first loaded the larger pellets, the AquaPro 75 clogged and didn't throw that first pellet. After multiple test throws and digging I gave up and walked away. The next day it started throwing those 1/4" pellets on it's own with no problem until the end of the season.
Bottom line is that my problems have been short lived and I have been pleased with the performance of my AquaPro 75 (knocking on wood). Check your battery cover, some of you may get lucky.
