Review on Kitchenaid 6 Quart Flex Edge Beater with Scraper - Upgraded Beater Paddle for 6 QT Bowl-Lift Stand Mixers, Mixer Attachments for 6 qt Bowl-Lift Mixers by Aaron Romero

I use this with my KA Professional 600. I tried it without anything in the bowl and it makes quite a noise scratching the inside of the bowl so I was worried it would it was too tight. Then I actually used it for what it was made for and I'm really impressed. I made bread dough with a dough hook and it didn't pick up any flour on the bottom. The batter was fluffy/light enough to use a spatula so I swapped it out for this whisk and 10 seconds later all the flour was incorporated. I've made several batches of cookies and I love how the edges of the spatula mix everything together without stopping, scraping the edges and moving on. The food lubricates the spatula enough that there might not be a sealing issue as I thought, but the spatula does an excellent job of scraping the sides of the bowl. It works great with my blender.
