Handy device. I put whole apples, pears, cucumber etc in it (without peeling), it went like clockwork. I peeled orange and lemon. Only very dry pulp remains, so all the juice is centrifuged out. The disadvantage is, if you want to add pieces, it will splatter a lot. Or you would have to turn the device off, fill it, and continue again, but I find that cumbersome.
Point of attention: make sure that the device is properly secured with its suction feet. I once had that this was not the case, the machine then made a pirouette and the juice was all over the kitchen :-(
But that was my own mistake. Otherwise great device. Fun to 'experiment' with all kinds of fruits and vegetables. You just put everything in it and taste it.
