Since fruit is a key ingredient in smoothies, good fruit blenders are often popular among smoothie enthusiasts. User opinions indicate that small-to-medium sized blenders are best for blending fruit. Unsurprisingly, these are also ranked very highly for juicing. Furthermore, plastic jars seems to outperform glass ones when it comes to fruit.
Tribest, NutriBullet and Vitamix are considered the leading brands in this category.
