I have this oven. It is quite basic, but I love the white glass and the fact that it has knobs instead of a touchpad. It is a great value for the price, including convection.

There is an electronic timer built in, it is a countdown timer, and I usually end up using a battery-operated one; it's just easier for me.

The functions are represented by icons, as this oven is sold in places where many languages are spoken. The icons are printed right on the left knob. One of the settings is for the light (light bulb icon). The convection icon is the three fan blades icon.

The oven beeps when it reaches the set temperature.
Here's the manual:

My complaint is that I wish the rails on the racks were closer together and/or stronger. But they are typical Whirlpool racks (they are the manufacturer, but NO name appears on the oven front).
