Need a good vacation timer. Any suggestions?

This timer cannot be programmed.
Timer has pre-set program to turn lights or appliances on-off at random times so home looks occupied. GE 7-Day Random Vacation Timer turns lamps or appliances on or off during late evening and early morning hours, confusing potential burglars.
Rotate dial clockwise until current day and time lines up with pointer, and plug in.

The Brinks 42-1009 EZ Vacation Timer is preset with 7 full days. You cannot choose when it goes on and off.

To set, spin the dial (clockwise only) until the arrow in the upper right of the center face is near the current day and time. Plug everything in and switch the upper tab to the right. On certain days, it will turn on in the early morning as well as evening or late night.

You cannot choose when to turn the light off. However, if you are home, you can turn the light on by switching the upper tab to the left. Remember to switch it back to the right in order to activate the timed on/off periods.

49750 sounds like a Woods timer number, but I can't identify for sure
Woods makes timers for many other brands that are sold under different numbers

Look closely at outer edge of dial and see that dial has small plastic protrusions that stick out.
These protrusions are trippers that cause timer to turn lights on-off at random times so home looks occupied when on vacation.

I believe the First Alert timer is same as GE 15151 vacation timer.

You need a 60 minute cycle timer capable of running 12 cycles per hour.
Usually this type of timer is heavier duty for commercial applications like garden irrigation or misting, stock feeding, or cattle barn ventilation. Commercial applications require reliable long-term product with higher price.
Average mass market plug-in timer is lighter duty, and is used for turning on indoor lamp or outdoor christmas lights a few times per day. These timers are inexpensive 'corner store' items priced at 6-15$. There would be no mass market for for a plug-in cycle timer as specific as your requirement.

Intermatic makes a panel-mount digital cycle timer you could wire to short extension cord.
