5.0 out of 5 stars Adjust your beater to bowl clearance to eliminate chipping November 25, 2008

By Momof 3

After reading these reviews, it seems that many people do not check their beater to bowl clearance. If a beater is chipping on the bottom, it means that it is too low. Sometimes, if the beater chips on the top, it means that the beater is actually too high, and the head can not lock properly, which can cause bouncing and chipping. You can look in your use and care guide, or go to kitchenaid.com to watch a video on how to locate the adjustment screw. If the mixer doesn't incorporate the ingredients in the bottom of the bowl, then the beater is too far away from the bowl. If you have a tilt-head mixer, the adjustment screw is located in the neck of the mixer-in the hinge-when you lift up the head, you'll see it. You can place a dime in the bottom of the bowl, and turn the mixer to "stir". If the dime moves around continuously, it is too low. If it doesn't move at all, it is too high and can't reach everything. It should scoot the dime around the bowl 1/4-1/2" at a time. I've had my beater, which is used a lot, for about 5 years, and it has no chips. If you have a bowl lift mixer, the adjustment screw is behind the bowl clip. If it's adjusted properly, you get the best mixing and the least wear and tear on your beater and bowl. The adjustment can change slightly over time.

5.0 out of 5 stars 5 star duty, 3 star replacement need January 5, 2003

By Michele Mucke

I have had my Kitchen aid for about 12 years, I love it! THe problem, as stated before, is the fact that the "metal" turns "bubbly" under the paint and the paint then starts to crack. This is not a favorable aging process. It does take several years to "turn", but when it does make you feel a little cheated, the price you pay for these machines shouldn't warrant this low-end occurance. While the beater lives it is SUPER! I make bread a lot in combo with the dough hook and it works great! Cookies, cakes , anything from scratch, you KNOW you'll be able to mix! Even something heavy or with nuts.. no problem! Kitchen-aid.. if you are reading this... Why ?! Why does this happen! The dough hook is still in prefect condition. I have other attachments and they are all heavy duty and GREAT!

2.0 out of 5 stars Works fine for a year or so until it's ruined. Now looking for 3RD replacement for this "disposable" item. December 12, 2006

By JAB

Who would've thought that these things wear out and must be discarded so often!?

I've previously purchased two of these as replacement beaters for our Mixer. They have each worked well for a year or so but then the plastic coating starts to wear away and falls off into your cookies/rolls/bread/whatever.

I honestly thought that the first time was a fluke but now that the second beater has shown the same problem I'd call it a flaw. I'm wondering if there is some other option for beaters that will NOT fall apart into my food after a year of mild to moderate use. I don't want to spend $15 every year on a stupid beater!

3.0 out of 5 stars WHY doesn't Kitchenaid make these out of stainless steel??? July 14, 2007

By Nosewiper

I own two KA mixers and have used them heavily over twenty years. These beaters DO have a durability issue, and to me it'd be easy to remedy.

The older mixer came with a whip made completely of stainless steel, and the coated beater and dough hook were also of a more durable metal. At some point Kitchenaid started substituting aluminum-- a material which corrodes in the dishwasher, bubbles up (under the coatings, even) and results in cracked coatings and nasty-looking attachments which don't slide onto the mixer shank easily.

I see that some higher-end mixers are available with "burnished steel" attachments--this might be just what Kitchenaid needs to start offering for the lower-end mixers. Or they could just go back to whatever they were using 20 years ago. These beaters are just a big blemish on the face of what is a wonderful appliance.

3.0 out of 5 stars Beater replacement due to nylon coating disbondment November 7, 2004

By C. Lamison

Due to the nylon coating coming off our old beater we are replacing our KitchenAid flat beater after 15 years of use. We note that product description says to "hand wash" and that perhaps 15 years of cleaning in the automatic dishwasher is the reason for the deterioration. Still this is the 21st century and you would think KitchenAid could come up with something that doesn't require 19th century cleaning techniques.

5.0 out of 5 stars Wash by hand!! February 29, 2004

By A Customer

I see some people complaining about the paint chipping on this beater. I have had mine for almost 7 years with no problems, but I was told by a professional pastry chef to never put the beater in the dishwasher, or even let it soak for a long period of time. I haven't and it's been fine. I am finally getting around to getting a second beater to go with my second bowl.

3.0 out of 5 stars Paddle Attachment December 12, 2002

By kim

I love my kitchen aid mixer! I use it all the time, expecially at Christmas time. However, the paddle attachment and other white coated attachments peel and chip. Who knows where it ends up? Probably in those cookies I'm feeding my family. Although I love my kitchen aid, the attachments need to frequently be replaced, therefore I rate this a 3.
