From the Highly Educated Website, "Optimized for a better user experience, the Gavel 3 features several improvements from the V2. These improvements include a deeper bucket, stronger welds, the removal of hard corners on the inner diameter, and lifting the opaque/clear weld for easier cleaning. These small changes make for major improvements when it comes to maintenance and the inclusion of an opaque wall allows the Gavel 3 to perform more efficiently when used with cold start techniques. "
