So after researching many products on the market i took a chance on this smoothie maker and am very pleased that i did. It takes what ever you throw at it and with ease. We tend to use frozen fruit in breakfast smoothies along with nuts and fruit and within 30 seconds its a completely smooth and delicious smoothie and i mean completely smooth. You can lock the cup into place on the base so it just keeps blending or use the push to blend function. Would highly recomend
