I know this may be a little off topic, but if anyone knows the answer to this its one of you folks. As best as I can find out the 2 primary models from Ballstar are the BCM201A and the BCM201M. I recently purchased what was supposed to be the newest model from an online vendor. He sent me the BCM201A claiming its the newest model. Does anyone know if that's correct? My experience has always been that the newer models have the suffix increase, not decrease. Seems strange to me. Any insights would be greatly appreciated. I think I've been swindled but I want to be sure before I take action.
