Sylvania SA170 15 Amp Zip-Set Digital Wall Switch Timer Review

This switch is good looking and very easy to use. The ZIP-set feature is especially useful if you use it to control outdoor lighting - it calculates the sunset time and turns on automatically at dusk. No more manual resets throughout the year. Installation is easy and the instructions are clear. It switches compact fluorescent (CF) bulbs.
However read this VERY CAREFULLY before you purchase this switch: it needs to be connected to a NEUTRAL wire. Many 2-pole light switches only switch the hot wire of the circuit and you may not be able to find the necessary neutral wire to connect this. Look into your junction box to confirm the presence of the neutral wire if you are replacing and existing switch. If you find only 2 wires of the same color connected to and around the old switch, you probably won't be able to swap in this one (or any other CF-capable digital timer switch) without rewiring the circuit.

Intermatic EJ500C Indoor Digital Wall Switch Timer Review

Intermatic EJ500C  Indoor Digital Wall Switch Timer

We purchased one of these four years ago to control our entry lights. That was the last time we touched it. The unit asks you to set the turn on - off times, and set the time and date when you install it, then you really don't have to do much else. With the auto adjust feature, it resets for daylight savings time, and one setting will automatically turn the lights on when it's getting close to dusk, then off at your preselected time - nice if you don't want to install a photocell or manually change start times throughout the year.
My only complaint is that the LCD screen is very small, particularly showing day of week, which means when you do decide to change times you'll have to really squint to see what you're doing. But fortunately, for most, this won't be a regular event.
