I've had the Boss Dogg for two years and have no issues other than the batteries (D cells) coming out of the tray when bounced around on the atv. A couple wraps of electrical tape around the battery pack solved that.
As far as battery life with a primos, they will drain fairly fast if cranked at full volume. Here in SW Mo. we have a lot of timber and small fields, so no need for high volume like in the desert.
One set of batteries will last me at least 50 sets.
As far as customer service goes, I thought they were great! I called them about the issue of batteries vibrating out of the tray and they offered to ship me a brand new unit, but I declined and did the electrical tape "repair" instead.
The Alpha Dogg and Boss Dogg are very large and heavy units. If I walked any great distances to my stands, I would want a smaller, lighter unit
