Round 3: Convenience

Dishwasher-safe parts
Rotating basket

Both Ninjas are extremely convenient at cooking food quickly, and while shaking is recommended, their large basket capacities sometimes means you won’t need to tend to your food. The functions aren’t complicated and both machines are simple to start up. Ninjas don’t come with presets, nor a viewing window unfortunately. They are both easy to clean up.

If you’re a bit of an experimental foodie, the Ninja OP350UK will spice up your cooking regime and is an excellent machine. But if you’re looking for complete meals, the better overall multicooker is the OP450UK. It offers more space and is extremely easy to use.
