Works just as described. I was a little leery of buying this but I was eating a lot of pineapple on weight watchers and I hated the pineapple prep. I have to say this gadget makes it so easy! If you get started crooked, the blade will start coming out the side of the pineapple. Just pull it out, remove the slices, and start again. Depending on the pineapples shape, you may want to finish the inside of the pineapple with a knife. Still beats peeling the rind off all of it! I've used this device many times and I'm satisfied with the quality so far.
