As multiple people have stated the beaters break apart in the mix. Replacement beaters are sent and they also break apart. There is no way to use this with beaters that do not function properly.

Wish I had listened to all the other reviews. The plastic covering on the beaters sheds off (into your batter/dough) after just a few uses. And somehow that's not covered by the warranty, even for such an insanely expensive piece. People have been complaining about this for at least 5 years, so I guess they can't afford to have the warranty cover it. Massive buyer's remorse. Huge disappointment.

This trash is not for serious people. It is both proprietary and GARBAGE. The whisks last a few dozen uses at most. They’re never been in a washing machine (like others I have that are years old), and the replacements all last a few dozen uses like the original junk. The best part is that their MBAs have decided to pair manufacturing garbage with making it impossible to get a replacement locally or buy upgrades that last like pro products. I hate this thing so much. This is not usable for anyone serious. Breville is for people cosplaying serious chefs only.
