Versatile 5-Speed 250 Watt Hand Mixer




Model: MX400B

Mix, whisk, and knead with the improved design of the BLACK+DECKER™ Versatile 5-Speed Hand Mixer. This set includes two professional-style beaters, two dough hooks, and one chef's whisk; allowing you to quickly create cake and cookie batters, bread doughs, spreads and dips, homemade whipped cream, or whipped egg whites for a tasty meringue. The 250-watt motor runs at five speeds, including a 20% slower* starting speed that keeps your countertop splatter-free. Plus, a special turbo boost increases the mixer to maximum speed to combine thick ingredients in no time. All accessories are stored conveniently in the smartly designed storage case, which uses the mixer itself as the snap-on cover. Cleanup is a breeze with the auto-eject button that quickly disconnects the dishwasher-safe mixing tools. Plus, you can further prevent messes with the bowl rest, which allows the mixer to sit upright on the edge of the bowl.

Rated 2 out of 5 by from Disappointed with product I bought this mixer about 3 weeks ago, but it has rectangular beaters. When I used it, it wouldn't cream butter and sugar but left big lumps of butter that I couldn't get broken up. I had to go on line to figure out where the eject button was to get the beaters released. I thought Black and Decker would make a better product. I can do gross mixing but nothing fine with these beaters.

Rated 1 out of 5 by from Broke after a few times Was excited to get a compact appliance with the various attachments that are dishwasher safe. Used about 3 or 4 times and the plastic inside the hand held portion broke, rendering it useless. Like to get a replacement. Typically Black and Decker is my go to brand in appliances, and extremely disappointed with this.

Rated 5 out of 5 by from This is the best mixer I have ever used! The low speed is powerful, but doesn't sling stuff everywhere. The high speed is so fast and smooth! I really like this mixer.

Rated 2 out of 5 by from The "helix" attachments don't work well I was hoping this would be a good mixer, and it's not totally bad, as the dough hooks work well, but the "helix" attachments are pretty useless, as they fling what you're mixing and don't really do well at chopping any solids. I wish I could get normal ones...then the mixer would be great.

Rated 5 out of 5 by from Perfect Back-up This was a gift to me to use when my stand mixer is in use, but I need a mixer. I love it!! I especially love the compact storage unit which keeps all the parts in one place. My case has broken (fell on the floor with force) and I would like to know if I might purchase another.

Rated 2 out of 5 by from good I just wondering why only come with 1 chef's whisk??

Rated 1 out of 5 by from unhappy I bought this to replace a broken mixer thinking "hey, black & decker, they're reliable". I do not like the beaters. They do not mix well. Takes a lot of effort on my part. My whipped potatoes never had pieces before. Took forever to mix cookie batter. I contacted them but got no response. So I am giving it away. Won't buy another one from them.

Rated 4 out of 5 by from Great mixer! I have had this mixer for a pretty long time but I am just now writing a review because although I cook a fair amount I don't bake as often and just started using it. I've had several mixers over the years but I really like this one. I love how light it is -- past hand mixers have felt really heavy which made it harder to use. As someone who doesn't enjoy baking as much as cooking I was worried that I was going to be wasting my time on this product but now that I have used it a couple of times I am sort of hooked! Not only is it a great product but it is a Black and Decker so you know you are getting quality! I would def. recommend this to anyone looking for a new hand mixer!

My easy eject button doesn't seem to be working

Asked by: 6grandkids
The eject button can be a bit finicky at times. Honestly, in my experience, it's the way you push it, like a back and down motion, in order to eject the attachments.

Hi i purchased this in the US but i was intended to use it in Argentina were we use 220 V and 50 Hz. Is it going to work ? Should i return it ?

Asked by: Saraybel
Thank you for your question. This hand mixer operates at 250 watts, 120 volts, 60 hertz, and 2.083 amps. Under the Key Features section there is a Specifications box that indicates this Black + Decker toaster requires 120 Volts – 60 Hz electric power service, such as that which is used in North America. Please do not attempt to use this hand mixer with any other electric power service.

Do you use the whisk by itself or with one of the other beaters? The instructions do not seem to address this at all....

Asked by: pamela13
We thank you for your question regarding your MX400B. You would want to use the whisk by itself and not with the other beater.
