I thought I liked this product at first because I was supposed to, but the more I used it the more I realized why I hated it. It clumps up half your batch of potatoes after mashing, and it does a TERRIBLE job mashing the potatoes. They come out all extra chunky and lumpy which defeats the purpose of mashed potates in the first place. Very dissapointed.
