This bulky blender comes with a big 56-ounce jar, so you can make large quantities of smoothies or soups at a time. It's very versatile as it can blend both cold and hot liquids, and it creates bar-quality ice quickly. Unfortunately, the jar's lid isn't the easiest to clean, but both it and the jar are dishwasher safe.

It can be somewhat difficult to clean the blades by hand, but the jar and lid are dishwasher-safe.

This blender comes in many different colors, including 'Almond Cream', 'Beetroot', 'Blue Velvet', 'Candy Apple', 'Contour Silver', 'Matte Black', 'Passion Red', and 'White'. It's sometimes sold with a tamper in various colors, including 'Blue Velvet, 'Contour Silver', 'Dried Rose', 'Matte Black', 'Milkshake', 'Passion Red', 'Pistachio', and 'White'. There's also a variant that comes with a tamper and a personal jar. That variant comes in 'Contour Silver' or 'Matte Black'.
We tested the basic version that only comes with the 56oz jar main in 'Matte Black'. We expect the other variants to perform similarly as long as you're using the main jar. However, we don't know how the personal jar will perform. The tamper will also affect the blender's performance since it lets you stir ingredients without removing the lid.
If you encounter another variant, let us know in the forums, and we'll update the review.
The KitchenAid K400 is a great all-around blender that performs well regardless of what you're blending. It also supports hot blending, so you can do soups or other hot mixes, like most KitchenAid blenders we've reviewed. It's also very well-built.

The KitchenAid K400 blender is quite similar to the KitchenAid K150 in terms of dimensions and is a bit bulky. It's not as tall as other blenders, though. However, it's very heavy, so you'll likely want to store it directly on your counter, as moving it around frequently can be a bit of a nuisance.
It has a great build quality. The base and its gears are made of plastic but feel sturdy. The gear on the bottom of the jar is made of metal, which is more durable. The control buttons also feel solid rather than flimsy. However, the jar doesn't feel as solid as other blenders', like the Wolf Gourmet Pro-Performance.

It's okay for nut butter. You have to stop the blender frequently, especially at the beginning of the process, remove the lid and stir the ingredients to keep them moving. While it's a time-consuming and hands-on process, it ultimately makes very smooth, spreadable nut butter.

Despite showing options from 1-5, you can hear the motor progress through 22 different speed increments as you slowly move the dial, giving you a good number of options for fine-tuning the blending speed.
There's a dial with indications for speeds 1-5 as well as four automatic blending programs: 'Icy Drink', 'Smoothie', 'Crushed Ice', and 'Self Clean'. The speed dial rotates smoothly instead of clicking from set speed to set speed, so you can make small adjustments. Turning the dial counterclockwise (as if selecting a speed before 1) activates pulse mode. The blender can hot blend but doesn't have any dedicated mode for soups and can't warm up cool ingredients.
This blender is decently easy to clean. Running the blender with soap and water in the jar takes care of a good amount of residue. However, the angled non-removable blades make it hard to easily clean the jar, and you may need to spend some time scrubbing them with a brush. If you want a full-size blender that's easier to clean, check out the Vitamix Explorian E310 or the Oster Pro 1200.
