Recently inquired about this because I was annoyed having to spend $150 for a cup and bowl but figured I'd just take the plunge.
Pros: Works and makes a smooth smoothie. Dishwasher safe.
Cons: Over-engineered. Expensive. Loud. Unergonomic. Only one cup capacity (20oz) . Cup has no measurements which is just silly. The seal is a bit annoying because it requires cleaning, moves around and can be hard to get back on the bottom groove properly
Off the bat there are no instructions and I could not figure out how to use it. Maybe I am dumb, but it was not as intuitive as a ninja. But basically you need to align this little lock symbol on the cup/bowl with a barely visible line on the blade attachment base you screw on. Then you place that on the base adapter thing by aligning the grooves on the side of the cup/bowl to the base. Instructions are on the website and also on youtube https://www.youtube.com/watch?v=a-Sna0_kXtI
As someone else pointed out, it is not ergonomic. God help you if you are weak or have any physical issues with your hands/grip strength.
Otherwise it performs very well and made an smooth milkshake like smoothie. It recognized the cup and adjusted the smoothie program accordingly. Easily the best personal sized smoothie I've had compared to other blenders. I forgot that personal cups tend to introduce a little less air which is nice.
