Got this last week when they had the deal w/ 2 cups. It is the Costco variant with the larger vessel. It appears to have the corrected lip that doesn’t retain stuff that causes mold/mildew. Been using it fairly regularly since it arrived with different beverages. There is a slight learning curve, I will say that you need to pay attention to your sugar content. Most notably spiked slushes need to be just right or it won’t slush & there isn’t much room to adjust the coldness. Most sodas & energy drinks are good right out of the box, with little adjustment. Frappe are straight forward. I’ve made mine w/ Stok slightly sweet black coffee & coffeemate sweet cream creamer, & it will work pretty straight away. The manual is barebones, & doesn’t have the recipes that the regular retail units have, however you can download the recipe guide from ninja. For the price I would definitely recommend getting it while you can.
