Not to be a damper, but you may not want to use it for apples. Don't want to burn out the motor and sleep in the dog house. Instead, you may want to look at a sink grinder setup that people do. Just due to the quantity and texture of the apples.
However, you could consider it for other fruit (raspberries, strawberries... even peaches minus the stone.
Though, if anyone else has used it long term for apples before, and says yes, then great!
