The Siemens studioLine BF922R1B1B is an iQ700 built-in microwave oven in black, with a right-hinged door. It is a microwave only, with no grill, which keeps it simple: 21 l of space, 900 W of power, a TFT touch display and seven automatic programmes, in a unit that fits a standard 60 cm wall unit.

Cooking

The stainless steel cavity has a glass base and holds 21 l. You choose from 90, 180, 360, 600 or 900 W, so it can boil a mug of water quickly or soften food gently at the lowest setting. Inverter technology eases the output back to 600 W on longer cooking for gentler results. cookControl7 gives seven automatic programmes, three for defrosting and four for cooking, so you don't have to work out power and time yourself for everyday food.

Controls and everyday use

Settings are chosen on a TFT touch display with touch keys. A single tap starts the microwave at full power for 30 seconds, handy for reheating a drink. The door is hinged on the right, opens sideways and swings back as far as 160 degrees, which Siemens recommends for a microwave fitted up high; a left-hinged version, the BF922L1B1B, is also available.

• Electronic button to open the door
• LED light in the cavity
• humidClean Plus uses vaporised soapy water to soften dirt so it wipes away easily
• Door contact switch and start button for safety
