Joan,
I wish your mixer a long and happy life. Sadly, that wasn't the case with the two we've had here at the club. Our pastry chef used it along with a Hobart 20 qt. The first one (7 qt.) died after just six months of use and Kitchen Aid replaced it free of charge. Six months later, the replacement died, and by then it was considered to be out of warranty coverage, so we decided to trash it rather than spend who knows how much just to get it up and running.
The 7 qt. Waring mixer we got is running strong and we're happy with it. The whip actually touches the bottom of the bowl, which isn't always the case with Kitchen Aid
I love my old 5 qt Kitchen Aid that I bought in 1983. Not a single issue with it, even though twice while kneading bread dough, it fell off the counter and hit the floor hard.
