I bought this machine to help distribute both alcoholic (hurricane slush) and NA (cola) drinks for our child's Mardi Gras gender reveal party. The machine was an absolute hit and easily holds 12 liters in both of its hoppers. It takes about 45 minutes for non-alcohol drinks to turn the slush and about an hour and a half give or take a half an hour to turn alcohol-based drinks into slush. The only part of this machine that is slightly confusing is that you will need to understand how the knobs in the back work. This is helpful in creating both consistency of your ice and getting it to freeze itself. It's not hard to figure out but it is worth understanding before you say that the machine is broken. I seem to remember that the instructions in the book are backwards. To help you out, if you adjust it to the left (counterclockwise) You will add additional freon to the compressor making it more dense. If you adjust it to the right (clockwise) You will give it less. Also, the outside will not freeze with non-alcoholic drinks but the way energy transfers with alcohol drinks the outside of the case will freeze, don't be alarmed. Enjoy this steal of a deal!
