Hi Toby,<br /><br />Thank you for taking the time to write a review. We understand how disappointing it can be when your margaritas don&#39;t slush correctly. When using the SPIKED SLUSH preset, all premade inputs (wine, beer, etc.) must be between 2.8% and 16% alcohol. If you&#39;re still having difficulties with slushing your drinks, please reach out to our support team at 1-800-365-0135. We&#39;re available Monday through Friday from 9:00 a.m. to 9:00 p.m. ET and Saturday from 9:00 a.m. to 6:00 p.m. ET. <br /> <br />Kind regards, <br />Ninja Kitchen
