Well so far I haven't used any bananas at all, I had a lot of frozen bags of fruit for smoothies such as raspberries, strawberries, blueberries and peaches and all them come to a great sorbet kind of desert.Using it is as easy and it sounds, you just put fruit down the chute and then push it in and soon ice cream looking stuff comes out and it kind of baffles me how it works. Looking at everything beforehand I thought it needed other ingredients or something but no, just the fruit. The Yonanas is comprised of 6 parts which are easily taken apart and cleaned also! I would highly recommend for people looking for a healthy way to snack
