Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. Some can even cover extra costs that result, such as cost of food that spoils when your fridge dies. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Appliances can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new appliances should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

The newer stand mixers are inferior quality

DMMS 5/1/2019

This is my 3rd Kitchenaid stand mixer. The first one was over 20 yrs old but I wanted to upgrade to a bigger unit. My 2nd mixer is a 6qt with the stainless steel bowl and after only a few years the motor gears were worn smooth so it's useless. Is Kitchenaid using foreign metals to make their machines because I'm not the only one this has happened too. The same thing happened to my sister in laws 6qt. My 3rd and final Kitchenaid is the 6qt with the glass bowl. I was smart and purchased the extended warranty, however this darn bowl is so heavy but worse yet it doesn't mix well at all. The bottom of the bowl doesn't even get touched. I've been constantly lowering the bowl to scrape it down. Furthermore, the rubber gasket ripped off by the third using. WhT the heck is going on Kitchenaid????!

Glass Bowl

Kathleen2000 3/25/2019

I agree with the reviewer from 2 years ago. You really need to have a stainless steel bowl option instead of the glass bowl. I knew the first time I used it that this was going to be a serious problem for me. It is far too heavy, difficult to attach and it is very difficult to clean the little pieces of smear that accumulate on the bowl during the proofing of bread sponge, even if I try to clean it immediately. I bake a lot of bread. I believe most of my older friends will have the same complaint about the heavy bowl and my younger friends won't like the hefty price tag. The primary reason I purchased is that I have hundreds of dollars in attachments.

Don't do it! Bad designs & no help from KitchenAid

r4roses 3/25/2019

If you want a mixer to sit on the counter and look pretty, go ahead and buy this mixer. If you actually use this for the workhorse that a 6qt mixer can be, keep shopping. The inside of the mixing bowl has chipped repeatedly with normal use! have we eaten this glass? Who knows? I wasn't baking with car parts! KitchenAid knows this glass is an issue: none of the beaters get anywhere close to the bottom of the bowl so you will constantly be incorporating the last of the ingredients by hand from bread dough to egg whites. And the rubber ring around the outside edge is impossible to keep clean. It's not removable and food and water get stuck underneath. If you wash too aggressively, it peels and fails. There is a 6 qt model with a metal bowl and it actually costs less. If you like the look of glass, get the lift head model. This mixer was a disappointment and not nearly as useful as my last model that worked for 15+ years. And if you want to bite the bullet and replace the bowl just to get you through the baking season? Nope this glass bowl is out of stock and the only metal bowl available for this model is 3 qt. What? Customer service could offer no solutions and wouldn't even trade down for the less expensive metal 6 qt model. High and dry - no fresh bread for Easter!

Total Waste of Money

Runawayfromthismixer 2/12/2019

Terrible. Broke in the first two minutes of using it. They sent me another that is pretty useless. The gap is too big to be useful, even with adjusting. Apparently this is due to an inconsistency with glass bowls - the service rep said it indicates this in the manual. Bought another brand.

Disappointed

Baking Fan 8/23/2018

I bought this to replace my 30-year old KitchenAid mixer which ran flawlessly for years. I am less than pleased with this model. This mixer came with the trim around the motor (with the setting numbers) unglued and loose. The whisk attachment does not reach the ingredients at the bottom of the bowl despite my adjusting the bowl height as described in the manual. This makes the whisk attachment unusable. Not the quality I expect from KitchenAid.

Great mixer

ATeam 6/17/2018

I got this for mother's day and I my family and i love it! Love the ability to add attachments! Love the features as a mixer too. The only negative aspect is that it's too heavy. I store it in a kitchen garage on my countertop but it's really heavy to move it around for daily use.

Nothing but trouble

Really! 6/15/2018

I'm someone whom used to swear By KitchenAid and was So excited to get one of these mixers for Christmas. I had done a few batches of cookies and some cakes and it seemed good until sometime in March when I was whipping mashed Potato's and it failed. I didn't know what I was in for until the exchange prosses! I got the replacement mixer and right out of the box the power switch was faulty so I call again and a kind lady helped me. then I received "two" mixers by mistake, One Black and One Red. so the Black one had the same Problem with the switch only working part of the time. I took the Red one out of the Box and it works fine "For now" and I called again and got a hold of a snarky girl that spoke over the top of me as I was trying to explain they have a Quality problem in the switch. so at the end of the day I have the Red Mixer that I did NOT want being everything in my kitchen is black! granted she offered to exchange the red one for another Black .. "to what End" it's been weeks of exchanging. I'm going to buy red accents and just keep it! at this point I'm just tired.

Beautiful and quiet unit.

Opa! 5/17/2018

We love our mixer. We had an accolade tilt head with a 400W motor (still works, we gave to my mother after 10 years of use) but this machine is so much quieter with the DC motor.. at level 10 you can have a conversation still vs a yelling match. The chrome hub just adds a nice touch of elegance. We leave it on the counter top since it's quite heavy but does look great with the glass bowl. Now the unit I found wasn't so heavy that you cant move/tuck it away, but could be for some folks. I also purchased the 3Qt bowl and whip for smaller batches and a 6qt stainless steel bowl. Yes, the beater doesn't fully touch the bottom .. hence why i got the smaller bowl for the smaller / liquid jobs. Only glitch I had was putting in the large SS bowl... took mew a few minutes but I think its because the back tab is still new and stiff. Best of all was the price. An authorized dealer was selling them on eBay and eBay had a promotion so my final price with tax and delivery was only $510 Canadian. The 2 extra bows I mentioned above I got directly from kitchenaid Canada, on sale as well.. with delivery and tax, for $210. I still have my attachments from my previous mixer thus I expect this will my last mixer I have to buy (I'm a light user.. once a week.. yes I know it was overkill).

Really Heavy!

Lady4str 4/17/2018

Received this as a gift. It is very heavy, so a weak person should have it placed where you intend to use it. I have not had it long enough to use it much, but I am having trouble adjusting the beater to mix everything in the bottom of the bowl, esp. with the additional stainless bowl I purchased. I'm anxious to see how it mixes bread dough. And, I just purchased the pasta accessories, so that will take some practice. The glass bowl is very heavy, and I noticed that the base of the bowl looked like it had been dropped--chipped area.

Redstoney 4/5/2018

My husband surprised me with this - something I have wanted for a long time. The first thing we made was cookies and it was a breeze! No need to stand and hold the bowl, spinning with the other hand. My daughter has used it many times as she is experimenting in the kitchen.

Best baking tool in my kitchen!

4Chickadees 2/23/2018

Right before our annual Christmas cookue swap my 15 yr old KitchenAid mixer stopped working due to thousands of batches of Christmas cookies, birthday cakes and chocolate chip cookies for school. A quick trip to the store to buy this mixer was a wonderful surprise. This machine is more efficient, has a bigger capacity and much more quiet than our last mixer. My 4 daughters and I bake almost every day and this machine makes it a dream! Thank you KitchenAid for helping us make so many delicious memories and for the years to come.

Beautiful Candy apple red!

kathleen9613 2/23/2018

I received my beautiful Candy Apple red mixer for a Christmas gift. Since I waited a long time to receive this mixer, I expected it to perform perfectly. After trying to make a cake and the buttercream to go on it I found out that the paddle and whisk attachments did not mix far enough down in the bowl. This made for quite a lot of stopping the mixer and scraping the bowl. It was very frustrating! The mixer also doesn't work st all for me if I'm making a small batch of anything.

shopperZ 2/8/2018

I love this thing! It's quiet and powerful. I bought extra bowls/beaters (large and small metal bowls), which makes for easy switching from one project to the next. I'm glad there was a rebate so I could afford it.

Have always wanted a KitchenAid mixer! Considered a smaller version but this one was hard to pass up! Still fits nicely under my 90s-era cabinet height. Love the glass bowl but would like to get a metal one for lighter duty recipies. Grey finish is easy to wipe clean after use! LOVE LOVE LOVE!

Kelly 702 1/29/2018

I bought this product a month ago and I don't know what I was expecting but I am a little disappointed. Neither blade reaches the bottom of the bowl and it is a bit tricky to get it off the stand and scrape it to get the bottom ingredients mixed in.

Quiet power

latjr 1/29/2018

I bought this as a replacement for an older KitchenAid stand mixer and couldn't be happier. I love the power, yet it's remarkably quiet. The glass bowl is great. While I read some reviews about not using it for smaller batches of doughs or to whisk just a couple of eggs, I have been able to use it successfully for all amounts.

Ease of use

Scansteph 1/9/2018

I received this stand mixer as an upgrade from my previous model and am extremely happy with it. It is quieter than the previous model, the bowl lift is very smooth to move, and I love that I am able to see my ingredients in the bowl to ensure even mixing. I used it for egg whites and had to use the beater and then the wire whisk in order to whip them, but even a heavy dough for cookies has been no problem for this machine.

Maxwell0987654321 12/21/2017

I bought this a month ago and I've used it to make marshmallows, breads, pasta, and other goodies. I gave it 4 stars because the whisk attachment doesn't quite reach the bottom of the glass bowl even when adjusted to its top height. Other than that, I love it.
