Things I liked:We were looking for a Smart Charger that wasn't too expensive and would do the job for the buys Air Soft Gun batteries. This one hit sweet spot for its price point, but there was some technical trouble forcing us to buy a 2nd. Things I would have changed:Please be warned, we had two chargers eventually become defrective. We asked Pyramid for another recommendatio, but they had us send us both chargers and sent us one back that was in proper working order. What others should know:We deal a lot with couple of the leading Airsoft Retailers. I have to say Pyramid has (by far) the best customer service. Any time we have trouble they seem to go above and beyond to help us out.
