Pros and cons

Pros

Mechanical pin controls provide a simple way to set repeating daily on/off periods.
Two grounded outlets and a dual cord allow the timer to serve two plugged-in devices.
The stated 30-minute intervals allow more schedule granularity than a single on/off time each day.

Cons

The daily schedule repeats at the same times, so it does not provide separate weekday and weekend programs.
Half-hour increments limit timing precision for devices that need shorter intervals.
