My kids love the Ninja US - Ninja Blast, yes I said kids! My kids are obsessed at making smoothies and this came in so good for them! Each kid can make their own flavored smoothie so easily. I don't recall getting a lid for the bottom where the blades are (We never used one) but would be a great option to flip the Blast upside down, take off blade and have a bottom to the drink instead of carrying the bottom half with the cup. A cover for the charge port I feel would be super significant so the bottom half could be washed properly. We are super careful not to get liquid into the charging port. The lid on the top ( to drink out of ) is really hard to pop up. Kinda have to push the button and pull on the lid. All in all this is a great product that isn't bulky and I could take this with me to work with out taking up tons of space. We leave it on the counter and it's just out of the way.
