Review: Great timer for pond fountain - I use this to control my pond pump. Super easy to set on off times. You set 2 times. One for on and one for off. You can set, I think 15 pairs of times. The times can be for a certain day, weekend, weekday or everyday. There are 6 different modes: 1) on: always on; 2) on/auto: turns on immediately and auto shut off at next scheduled off time; 3) on/random: turns on immediately and shuts off at a random time around the next scheduled off; 4) off: always off; 5) off/auto: turned off and turns on/off at next scheduled times - this is the mode you want for it to follow the schedule exactly; 6) off/random: turned off the turns on/off around your next scheduled times. What I do is have 2 times per day when my fountain comes on. If I want it on at other times, I change the mode to on/auto so it will turn off at the next scheduled off time. It can turn on or off at dusk or dawn, but you cannot say turn off 30 minutes after on at dawn. I'm not sure how that my off time ended up being after the on time. I guess I assume it would turn on and not off again until next scheduled off time so you would have to keep updating the off time. Other than that, I love it,
Review: Works perfect. Easy set up & increments sunrise suntset perfectly. Plus can do more complex On/Off multiple times a day. - Doing perfect job. I have sunlight sensor on my transformer to turn on and turn off 25 LED landscape lights. Worked fine on new landscape but when Yuletide Camellia has grown and sun angle getting low or cloudy day they never go off because location of sunlight senor it is always little too dark so lights staying on 24 x 7 especially on cloudy days. I ordered this device, programed it according to instructions now lights come on at precise Sunset per Weather Channel and go Off at precise sunrise. During the setup process instructions you set the Year Month Day and Time plus there is a map you designate your region location (longitude impacts sunrise/sunset) and enter current day sunset time you can get from Weather Channel app. Then it increments the daily Sunset Sunrise perfectly in sync with that reported by the Weather Channel app. Saves electricity as well as reduces the hours on LED lamps. Granted they use lower power and have long life. But the LED long life part is theoretical 10,000 hours and not actual and they are expensive to replace so no need them being on during the day.

### ⭐⭐⭐⭐⭐ Feels quite solid and sturdy. The instructions cover all the features
*by J***A on January 5, 2015*

This timer works very well and appears to be very well made. Feels quite solid and sturdy. The instructions cover all the features, but are hard to follow. I found programming it to be quite easy, once I understood it. I suppose it depends - some people didn't have any trouble programming their VCRs, while others stuggled. I could could always program my VCR :-) It allows you to review all the on/off events, and change any single one - so if you make a mistake there is no need to redo the entire program. You should carefully review the on/off events after you think you have it programmed correctly to verify. In my first attempt I accidentally had an extra event that caused it to turn on a midnight. It can operate without the battery as long as it plugged in. So I suppose you could change the battery without it losing the programming by keeping it plugged in.
