Query: POOR PERFORMANCE

I HAVE OWNED SEVERAL AUTO CHARGERS BEFORE THE POWER DOME AND I HAVE BEEN HAPPY WITH EACH OF THEM. THEY HAVE WORKED VERY WELL AND HAVE SAVED ME FROM A NUMBER OF BATTERY PROBLEMS. UNFORTUNATELY, THE POWER DOME HAS FAILED MISERABLY AND I WILL NOT GET ANOTHER ONE. I AM WRITING THIS REVIEW AS I SIT STRANDED AT MY OFFICE WHILE A RELATIVE COMES TO PICK ME UP. THE POWER DUMB IS NOT WORKING AND I AM DISGUSTED WITH IT. I WILL INVEST IN SOME OTHER TYPE BUT NEVER THIS ONE AGAIN!
