Tough but tender. For us that sums up the capability of these amazing blenders from Viking. They're available in engines with either 800 or 1000 watts of pure power and either one provides more than enough brawn to knead any dough into complete submission. That's the tough. The tender is the wide range of settings that are delicate enough to whip up even the lightest, fluffiest, and most sensitive meringue you can imagine. This mixer also comes complete with a one year guarantee against manufacturer defects and that's just smart.
