(This review was collected as part of a promotion.) I waited  so long for the flex edge beater, for the 6 qt bowl.  I guess I should have waited longer.  My model is the KP26M1XFQOB,  It is so tight in the bowl it wouldn't  even go on properly, never mind trying to turn the mixer on.  As a mater of fact, I'm not even crazy about the 6 qt lift mixer.  The shield to put the ingredients thru does not fit properly, keeps coming off (and I have tried more than one), it also doesn't get all the ingredients mixed on the bottom of the bowl, even adjusting the bowl.  I'm totally disappointed with it all !!  I would have been happier spending all that money on a new TV or tires for my car. My mixer is now another dust collector, an expensive one I might add. I'm sorry I gave it a one star rating, but zero stars isn't an option.
