Heavy Duty 7-Day Digital Programmable Timer w/ Astro Feature (White)

My Application f the product was for Shore lights. The lights needed special timing, On 60 min before sunrise then off, On 45 min before dark, off at 1:00AM, It had all the features needed to accomplish the job. This is the second one I bought : - )

This is truly a genius piece of technology.-- especially the inclusion of the Astro feature. It's truly a 'set it and forget it' scenario -- on at dusk, off at dawn, and tracking the actual dusk and dawn times through the year. Like another reviewer here, I spent most of my career as a technical writer, and I totally agree that the installation instruction need improvement. I was able to figure it out, but it took quite a bit longer than it should have. Four stars for a great product with no so great documentation.

I replaced my 20plus year old driveway lights timer with this brand-new item and it was a perfect fit. Compact, modern looking with a small display window and a little bit of flair, I like it!.

Replacing a15+ year-old Intermatic with this unit was straightforward. Legacy design uses AA battery, current model requires far less common CR2 type. Programming is more complicated for newer system and instructions are vague at best. I've wrtten technical manuals for 20+ years, Intermatic needs to improve this model's user documentation. Astronomic feature is nice update, though implementation is mediocre. Of the mainstream in-wall timer choices, this is average offering.

I use this for my front porch light. No neutral wire at switch so this was the only option. It has only been about a month but has been working well and seems to be adjusting for the sunset on time. I gave it 4 stars only because of the short in use time. So far very happy.
