So I didn't actually buy this masher to mash potatoes -- I wanted to mash strawberries. And I have to say it did an excellent job! I got great, juicy mash for delicious strawberry shortcake and yes, everything  the ad claims is true -- it was a great fit for my hand; easy on my wrists; I was able to mash quickly a large quantity because the round masher plate cut through more space than the narrow wire masher I had before. It's stainless steel and not coated with anything icky that is likely to come off in your food.  I like the weight and feel of this product and it cleaned up in the dishwasher like a breeze. And yes -- it works great on potatoes too!!
