Sunpak ACC-M1060-01 Compact Rapid Nimh Charger Kit
was fine but died
at first, this product was fine and did what it advertised.  after two weeks and just 5 or 6 recharges it blew out one of the batteries.  Now that port is not useable and the battery is dead.  Maybe I put it on for too long, but it advertises a timer that prevents overcharging.
