For about $20, this peeler has a vacuum seal base and is capable of peeling, coring, and slicing apples, pears, potatoes, etc. I've only tried it with apples so far, but after 12 lbs. of apples, it's still working great.
So how's it work? Well, you place the apple on the 3 prong fork, and rotate the handle which moves the apple towards the peeler blade.
Keep turning and it hits the corer and slicer. Once the apple goes all the way through the corer, pull the sliced apple off the core, and pull back on the fork so that the core comes off.
The apple is actually one big spiral - pretty cool, huh? Even cooler, stand the apple back up, make one cut across the middle, and you have perfect slices. This, my friends, is a game changer!
