I like this corer/slicer very much and the results that it produces, but the criticisms of it are largely true. It does take some effort to use. I am 77 yrs old, but I am also fairly tall (63), so I can get a good bit of my upper body over the tool when using it to bear down. I usually get it done in one very hard push, but occasionally have to give it a second push. On rare occasion I have had to hit the handles with the palms of my hands to knock the cutter all the way down. I can readily see that shorter people might really struggle with using the tool since they would have to do all the pushing with just arm strength. Also, based on my experience, the product is likely to fail within a year of regular use. The tack weld on one of the blade pairs broke on mine (see attached photo). I had no problem with the plastic breaking, as did others, but it doesn't surprise me that such failures would occur. The problem lies in the force necessary to pass the 16 blades and the circular corer through the apple. It's simple physics -- more blades, more force, more stress. Mine lasted about a year with almost daily use on one or two apples, so, for around $25, I'm happy to buy a new one every year.
