Query: BAD PURCHASE

I HAD A 1,000 WATT MICROWAVE FOR OVER 10 YEARS AND WHEN IT STOPPED, I PURCHASED THIS SANYO, IT SAYS ON THE MICROWAVE 1,000 WATT, THE ONE I HAD BEFORE HAD 1,000 WATTS, ON THIS SANYO THINGS THAT TOOK 4 MINUTES BEFORE NOW TAKE 5 MINUTES AND WHAT TOOK 9 MINUTES BEFORE TAKE 12, IT MAY SAY 1,000 WATTS BUT IT DOES NOT WORK LIKE A 1,000 WATT MICROWAVE OVEN MORE LIKE A 800 WATT OVEN. I WILL NOT LOOK TO REPLACE MY SANYO WITH EITHER A PANASONIC OR SHARP. I AM VERY UNHAPPY WITH THIS ITEM.
