Since the I bought my hyperions all is smooth sailing. MRC looks good on paper with specs and features but unfortunately they have always failed for me. I understand that this is the same with their model RR products as well.
MAKE THAT 4, MY MRC DIED AS WELL....THE POWER PLUGS MELTED AND IT SIMPLY JUST SHORTED OUT...I ALREADY HAD A HYPERION THAT WAS OLDER THAN THE MRC AND IS STILL WORKING....MRC=JUNK.......GET A HYPERION CHARGER
