I have an american hunter with the varmit buster. I haven't hooked the varmit buster up yet. I got the feeder for Christmas and it was supposed to be for hunting but I figured why not use it for fish too. When I hooked it up the battery was dead so I charged it and it was fully charged and the next day it would be dead again. I called them and they told me its probably the battery. (Well duh!) So I guess I have to buy a new battery. They also said the solar panel isn't really a charger. (WTH is it then????) I have a lantern battery in it for now. I am looking to get the right one soon.
