I find that you waste a lot of zucchini and squash with this product. The spiked base which holds the zucchini on is much too small. It cannot get a grip on larger zucchinis because it only grabs into the seeded section.  The base just drills into the zucchini and causes it to quit spinning. The only time I have any success with this is when I use it on small very firm squash.
