Comfee CMSN 20 si: what works, what doesn't?

What works well

  • Simple dial operation: two dials and a clearly readable control panel, no menu, no learning curve
  • 20 L for frozen pizza: according to the manufacturer, the cavity takes a standard 25 cm frozen pizza
  • 5 power levels: more gradations than basic 3-level devices, so more flexible for heating and cooking
  • Interior light: the cavity is lit, so you can see how the food is getting on
  • Removable glass plate: the 255 mm turntable can be taken out for cleaning

Points of criticism

  • Only 700 W: at 700 W it heats more slowly than 800 W devices, though that is usual for compact solo microwaves
  • No grill or hot air function: a pure solo device, so gratinating or browning is not possible
  • Mechanical timer: without a digital time display, the remaining time can only be read roughly

Build quality & everyday use

What carries the Comfee CMSN 20 si in everyday use: simple dial operation (two dials and a clearly readable control panel, no menu, no learning curve) and 20 L for frozen pizza (according to the manufacturer, the cavity takes a standard 25 cm frozen pizza). We have to be honest about the weaknesses: only 700 W, because at 700 W it heats more slowly than 800 W devices, though that is usual for compact solo microwaves.

If you set the device up to save space, make sure it stands on a stable, level surface with some air around it. This protects the mechanics and electronics in continuous use.

“Comfee CMSN 20 si Solo Microwave: simple dial operation and 20 L for frozen pizza, and the trade-off is only 700 W. At 8.0/10 a fair deal from €57.”
