All MVP trial participants found our product to be successful in preventing spills. They each used the Sip 'N Clip for 3 days, and completed a Google Form Survey following this period. Here is a link where a copy of our form can be found, showing the exact questions we asked participants. If you purchased a Sip 'N Clip of your own, we would appreciate your feedback as well. Feel free to complete the Google Form with your own suggestions so we can continue to grow as a business and adapt to your wants and needs.
