Powerful and no clumps!
This is a great cup. I hate how powder is always getting clumped. This is a VERY powerful spin. My daughter turned it on while it just had water in it, and it went everywhere since the lid was not on. The cup mat is built into the bottom of the cup. But the cleaning brush was not included as stated in the picture, that is the reason for the lower star review. Otherwise this is an awesome product.
