I like that it is 24 hrs. I outta 3 smoothies is good. Every time I have gone in you leave smelling like old fried grease... Or something. Can't pinpoint the smell. Its not clean at all. None of the containers on the counter with protein powder or oats have lids. Everything is always open. I keep thinking maybe next time will be better....... Nope. Problem is it is right by work, I'm so torn.
