I found the Yonanas simple to use and it allows me to add pure fruit, healthy deserts/snacks to our diet.
I have found that frozen peaches work as well as bananas and some of our grandchildren like the alternative to banana flavor every time.
I do consider the end product to be more like sorbet than ice cream.
I am a member of weight watchers. On the plan fruit is 0 points so this machine is very popular. I love it. It makes a smooth ice cream like dessert using only fruit. But you have to freeze the fruit over night, and let it thaw a bit before you make your treat. The directions say to freeze it hard, then let it thaw until it sweats a bit. Other wise you may burn out the motor, like someone on this list of reviews. When all else fail read the directions.
this small machine might be loud, same as a blender, and slightly expensive, but I love it and use it almost everyday. The texture of the ice cream is perfect and I love how you can put almost any frozen fruit or even candy in. The machine can be difficult to clean but it is extreme easy to use and dependent. I love the yonanas machine and there is nothing else like it.
