15-Amp Heavy Duty Astro In-Wall Digital Timer is rated 4.4 out of 5 by 116.

Found an intermatic you tube video that was much easier to follow and had no problem programming following these instructions. I wish it had the option to add a dimmer to the timer. But once you program it,,,,you can forget it; it will automatically change to new time changes in the fall and spring.

The ST01 is reliable and I have had these for a number of years and added some to a new house. I actually worked in tech support for Intermatic so I know these timers well. These are not quartz time based so every December go to the setup area and adjust the time. They never lose but can gain a minute or so per month over a year. I use these for the astro function for outdoor lighting and for a single fixture kitchen light to turn on and off randomly so it always looks like someone is at home.

Rated 4 out of 5 by from Replacement for 20 yr. old timer After a month of use, I love the astro feature! Here are a few things I learned. 1. It does not adjust daily. My astro feature changes about once a week in September. 2.The dawn and dusk times can be adjusted. Mine is set to go on about 15 minutes before dusk and go off 15 minutes after dawn. 3. It is difficult to hold a flashlight to see display, press buttons, and read directions or watch video all at the same time. Use a headlamp or get someone to help. 4.Compared to my old Intermatic Model SS7C, the click when it turns on is very noticeable. Overall, I am pleased with this timer. It is so convenient to set it and let the timer do the work.

It is very easy to install and the guide was simple to understand. Took me all of 10 minutes, beginning to end. Just be careful with the battery cover, mine took a little bit of force to open. Had to be gentle but firm to avoid breaking any of the plastic. Great timer so far.

The first one worked like a champ -- easy to program, cookbook instructions worked as expected. The second one, when installed exactly the same way, clicked on and off repeatedly when either I manually over-rided it or the program tried to turn it off (or on).

Also very unhappy with the size of the numbers and symbols on the tiny screen. The buttons provided to program the functions are also impossible to read. I used a flashlight and magnifying glass to set it up.

I've installed one similar switch in the past that did not require a battery. I don't understand why this one needs one -- I'd rather have the switch entirely powered by the wiring. That said, it works fine. Pretty easy to set up.
