KitchenAid K400 Variable Speed Blender - KSB4027

I've had this blender for over a year now, and it is my favorite blender by far.We have a vitamix I've used at work for years, and this matches it in blending power and consistency for sure. It is easier to clean since the bottom of the blender is a bit wider, making it easier to scoop food out of it. It has a self-clean mode that works well. It is loud for sure, but so are most of the blenders I've used. I've used this blender 2-3 times a week for a year and it is simple and easy. As far as the folks complaining about the controls, I just don't get it. If you want to blend like on a vitamix, you select your blend speed on the 0-5 range and blend. If you want to make a smoothie, you select smoothie and push the start button. It has a built in timer and stops when it's done. Want to crush ice? Select ice crush. That's seriously all you have to do. It doesn't get much easier than this folks. I guess people either refuse to read a quick guide or won't do anything their smartphone doesn't control for them.I definitely recommend this blender for anyone looking to spend less than Blendtec or Vitamix but able to spend enough for a premium blender. I am not paid by kitchenaid and bought this myself.

I’m not sure why there are so many bad reviews, it almost kept me from purchasing this blender but I love my KitchenAid stand mixer so I decided to get this to match. It’s by far the best blender I’ve ever used—it’s heavy and feels durable. I’ve been making smoothies, salsas, and açaí bowls almost every day since it arrived. The presets for crushing ice and blending drinks are awesome and work great! It also has specially designed blades that pull the contents down so everything is always evenly blended.The only con I have is that it’s very loud but it is a POWERFUL blender so I don’t mind. I also think for the price it should come with a glass pitcher vs plastic. The gear that turns the blade is plastic and I worry about longevity but time will tell. Overall very pleased with this blender!

Extremely powerful, quickly breaking down large amounts of frozen fruit. Pretty quiet low freq sound, not the high pitched whirring that drills into your head. I had a Vitamix that I never used as it was too bulky. I store the blender under the cabinet and slide it out from under, then slide it back. The Vitamix was like a tank. This blender is pretty heavy but has slots on the bottom sides that make it much easier to stick your fingers in and slide than the Vitamix. Love the durable plastic jug that is light and cleans up easily inside, with large sturdy blades. Super attractive for a blender!

I didn’t get this blender for free as the other reviews, I paid for it, and it’s kind of expensive. Blender is good! I’m very impressed with the quality and the way it blends. It’s a little loud but it does its job. I Will recommend for now.

Perfect for our morning smoothies! It has enough power to handle frozen fruit and produce a great smoothie.

Looks good. Nice styling. Great performance

The media could not be loaded. I really wanted Vitamix to be my ultimate blender and join the ranks of the coolk kids. But after buying two different Vitamix models and the Kitchen-Aid K400, I simply liked the K400 better and returned the Vita-hypes. Don't you love it when you like the cheaper thing better? 99% of my blender use is for smoothies and protein shakes (usually one of each per day) and the K400 just worked better for me. And it was great! Until...The seal failed, releasing a very foul-smelling grease (mostly out the bottom, from what I can tell). I contacted KitchenAid customer service—a laborious task; whether by phone or by chat, set aside an hour of your east-coast-hours-only day (I'd recommend calling). But, when you finally get somebody on the line, they are very helpful.For some reason, they can't just give you a replacement jar, and have to replace the whole blender. Whatever, I'll take it. It took a couple weeks, but they shipped out a whole new blender. So, in that regards the warranty is an A+.The replacement blender worked great... for another ~3 months, before... another broken seal. So, another hour of multiaskting-at-work later and I have yet another new blender a few weeks later. Surely it was just coincidental bad luck to have two bad blender jars? Nope. Here I am, 6 blenders later (or has it been 7 now?). Which brings me to this review and me giving up on this blender that I otherwise love.I suppose if you only use the blender once a month or so, it may last you for years. But if you're using it daily for moderately blendy blending it WILL fail.UPDATE Feb. 2025:So this last warranty-repacement blender I received lasted ~6 months before the jar began to leak. So here I am again requesting a warranty replacement from Kitchen Aid. Except this time, suddenly customer service is telling me that some of the broken blenders were never received back by them (they want the broken one back, which makes sense—and it's pre-paid, so no problem). But I sent them back. Of course, I don't have any way to prove I sent them back, as it was over a year ago and those shipping receipts are long gone. So, they ARE NOT honoring a warranty replacement this time. I don't blame the customer service rep; her system is showing that I have 3 blenders that were never returned. But also, something is broken in their system, because I'm not over here hoarding blenders. So, because their system is broken, I'm out of warranty.The funny part about all of this... not funny, ha-ha, but funny ridiculous... is that when the customer service rep was going through my "file" (yes they have a FILE), it did not even phase them that I've gone through so many blenders (a total of 7!). I explained about the leaking seals, and they just sorta say, "uh-huh." They don't seem at all surprised that the blender has broken so many times, which suggests to me that this is very common.Your mileage may vary.

I am obsessed with this blender. It works great with ice and my smoothies. I bought the individual extension since the one it comes with is so large. The cleaning feature is magical. It practically cleans itself. I researched for a good two hours on the blender I wanted after my ninja and am glad i went with this.
