I have the 480D however this review applies to this model too. I love my little blender! We drive a big rig and I use it every morning to make my smoothie. My unit blends perfectly every time! However, Ninja you have what I think is a design flaw. The threads for the blender blade and lid are on the inside of the container, when they should be on the outside of the container. I constantly get food debris in the threads where they get trapped and I have to clean out the threads while the smoothie is in the container so that I can get the drinking lid on. Then later it’s difficult to clean out the container due to part of the drink being left in the threads. I can’t always rinse it out right away, remember we’re traveling down the road, so when I try to clean the unit the lid is practically glued to the inside of the container — sometimes it takes me many minutes to get the lid off, or I have to have someone help me to get it off to wash. 

Ninja — please fix this issue!
