Using this timer, we did a retrofit to enable our new front porch chandelier to be an automatic dusk to dawn light. It was easy to switch out the existing light switch inside our house with this timer. Although the lettering is quite small, it isn't difficult to program or operate. Having the option of colors made it easy to match the existing light switches so it doesn't look like an afterthought, even though it was.

Good timer but….the indicators on the screen have poor contrast. (could not find AM). Also, the printed instructions are in such small font to be useless.

This timer is exactly what I needed!
