Answers

Frequently asked questions

Which is easier to set up, the Kitchen Mama or the Black+Decker Spacemaker?

The Kitchen Mama Auto, by a wide margin. It needs only 4 AA batteries and works immediately, no tools or mounting required. The Black+Decker Spacemaker EC600 requires a one-time under-cabinet installation with a screwdriver or drill, typically taking 15 to 20 minutes.

Which has more motor power, the Kitchen Mama or the Black+Decker Spacemaker?

The Black+Decker Spacemaker EC600, since it's a corded design rather than battery-driven. This shows up most on large or dented cans, where the Kitchen Mama's battery-powered motor is more likely to need a second pass or occasionally stall, while the corded Spacemaker maintains more consistent torque.

Which is better for a small kitchen with limited space?

Both solve the space problem, just differently. The Kitchen Mama is compact and cordless, so it can live in a drawer and never take up counter space at all. The Black+Decker Spacemaker mounts under an existing cabinet, freeing both counter and drawer space, but only if there's suitable cabinet clearance to mount it in the first place.

Which one should I buy if I'm not sure?

Choose the Kitchen Mama Auto if you want the simplest possible setup and cordless flexibility, and don't want to deal with installation. Choose the Black+Decker Spacemaker EC600 if you're willing to install it once in exchange for a permanently mounted unit with stronger corded torque and no batteries to manage.
