Overall I found this product very good. However it should be pointed out that you cannot peel without also slicing the apple, and slicing involves making a big spiral. Therefore you cannot use it for baked apples (just coring and peeling), and the slices, once you have cut up the spiral, come out quite thin, so you get no chunky bits in your apple pie! Having said that, my son likes the apple spiral and that's worth it!
If I could make one modification it would be to have the handle fixed to the screw, so you can just twist it on each time. At the moment you either have to get out a screwdriver every time you use it, or keep it out of its box (which it doesn't fit in with the handle on).
