I am pleased with both the products and delivery of my BatterySpace order. The batteries and chargers arrived in a reasonable amount of time, packed well, and preliminary testing of each product was favorable. Although it is too soon to know the long term utility I will gain from these items, I feel that I have found a good supply source. Thanks, Rick B
