Budget full-size
Hamilton Beach Big Mouth Duo Plus 12-Cup

What it gets right
- Two bowls for the price of one: 12 cups for batches, 4 cups for small chopping jobs, and they nest together for storage
- Published 500-watt motor at a budget price — a figure most machines at this money never state
- Big Mouth feed chute is listed to take whole tomatoes, potatoes and onions, which cuts the pre-cutting
- Wipe-clean touchpad and dishwasher-safe removable parts, with BPA-free food zones
What it doesn't
- No dough blade and no adjustable slicing thickness — one reversible disc and an S-blade is the whole kit
- Build quality is plainer plastic than the Cuisinart and KitchenAid
What it costs to run
About $1.59 a year in electricity, at 3 minutes a day, 365 days a year and 17.45¢ per kWh.
Hamilton Beach's Amazon listing for the 70580 states a "powerful 500 watt motor" with 2 speeds plus pulse. No continuous-versus-peak distinction is published. The full arithmetic is published.
Skip this if…
…You make dough, or you want fewer parts to wash — the second bowl is a second lid and a second thing to store, and with no dough blade in the box this is not the machine for bread or pizza.
