Toshiba ML-EM31P(SS)/CA 1.2 cu. ft. Microwave

A practical mid size sensor microwave for reheating, held back a little by its 900 watt output.

The short version

Buy it if
  • Apartments, condos and offices that need a mid size countertop microwave
  • People who mostly reheat leftovers and frozen meals
Skip it if
  • You want built-in or over the range installation
  • You cook large frozen items often and want 1,000 watts or more
  • Your counter is shallow, since the unit is over 17 inches deep

What owners like

  • Sensor reheat keeps leftovers and frozen meals from drying out
  • Turntable is large enough for full dinner plates
  • Simple controls and the option to mute the beeps

Common complaints

  • Stainless front picks up fingerprints
  • Loud operation at high power
  • 900 watts is slower than higher wattage models

Based on Toshiba Canada's product page, the Amazon.com and Amazon.ca listings, and a hands-on review of the closely related US model EM131A5C-SS. No independent review of the 900 watt Canadian model was found, so performance themes lean on its US sibling..

What it does

A 900 watt, 1.2 cubic foot stainless steel countertop microwave with a humidity sensor, sold by Toshiba in Canada.

  • Humidity sensor that adjusts reheating time to the food's moisture
  • Six sensor auto menus plus a popcorn button
  • Eco mode for lower energy use
  • Sound on/off, per the Amazon listing
  • Two step child safety lock
  • LED interior light and an easy clean interior

A sensible mid size microwave for reheating and everyday cooking in a small kitchen, with sensor reheat, an eco mode and a mute option. The trade-off is power: at 900 watts it heats more slowly than the 1,000 watt US version of this design, and the stainless front shows fingerprints.

How it compares

Toshiba EM131A5C-SSThe US version of this design with more wattage and 12 auto menus, if you want faster heating$$
Panasonic NN-SN686SBetter if you want inverter heating for gentler defrosting and more even results$$$
BLACK+DECKER EM031MB11A smaller, cheaper option if counter space and budget are tight$
