The listings show both AA and AAA batteries: some models require 1 AA alkaline, while others require 1 AAA alkaline.
The listings show common alarm features such as snooze and dual-alarm capability. Some models highlight a large snooze button and independent dual alarms for separate settings.
Displays are described as large digital readouts: one model has a large LCD display, and another features an extra-large 1.8" LED time display with easy-to-read digits.
The clocks can be wall-mounted or set on a desktop using a kickstand. Some models also include a tilt-and-swivel top panel so the face can be angled for optimal viewing.
Between the two listings, sizes vary: heights range from about 4 to 7 inches, widths from about 6 to 8.9 inches, and depths from about 1.2 to 8 inches.
Product details list plastic construction with black clock faces; one listing also describes a black frame with silver trim.
Review summaries note good value for the price, clear large digits that are easy to read, useful temperature reporting, convenient swivel positioning, and an overall functional design.
