I really, really love this product. Bed, Bath & Beyond sells 2 different models--the other is stainless steel and costs about double, but I can tell you the plastic one works just fine.
I love pineapple, but it's such a sticky mess to process, and dang near impossible to get rid of all that rough husk and chewy core. Not anymore! I'm telling you, this tool makes it so fast and easy, I want to have a pineapple party. I could buy a whole stack and just keep coring and wedging them all day long.
For 10 bucks, how can you go wrong?
