Vitamix Explorian E310 vs Explorian E520

You may prefer either the Vitamix Explorian E310 or the Vitamix Explorian E520. The biggest difference is their capacity: the E520 has a 64-ounce jar, and the E310 has a 48-ounce jar. The E520 is a bit better suited for processing large batches of fibrous ingredients and ice-crushing. It also has a few automatic blending programs and a pair of tumblers with straws. They're meant for serving drinks like smoothies, but you can't use them for blending, unlike the personal jars that usually come with blenders. On the other hand, the E310 a much better choice for processing small batches of fibrous ingredients, like for a single-serve smoothie.
