We are on low carb diets and frequently replace pasta with eggplant and zucchini. This attachment works well on a large, fat zucchini fresh from my garden, but I have had no luck with eggplant -- too soft such that the skewer just spins inside the veggie. I will try one more time by first peeling the eggplant and then VERY SLOWLY allowing the blade to contact the vegetable to see if that makes a difference. Waste is also a problem, because a cylinder of veggie about 3/4 inch thick remains when the device has finished cutting off the sheet. One must plan ahead as to how one can use the left over cylinder to avoid wasting it. Also, you can reduce waste by selecting fatter specimens of a veggie and specimens of a length close to 4 1/2 inches or a whole multiple thereof. I can allow zukes to grow to the appropriate size in my garden before harvesting them, but most store bought zukes tend to be too small and of the wrong length to be used efficiently.
