I had one of these timers and I loved it. So I bought 3 more. I use it during the holidays to turn on my spot lights displaying my Holiday decorations!I liked it so well I brought another one. Use it for outside lights. Set the time and it comes on every night at same time don't have to worry about going out to check on it.I purchased two and would like to preface this review with, one is working without issue. I have to give a ONE STAR review though, because the other one caught fire. I live where we have a lot of rain, and one was in the open, the other under an overhang. The sheltered one is fine. the one that got wet melted, shorted several strands of lights and could have caused a serious fire. For this reason, I advise caution in purchasing. I had used this for about ten days for the Halloween season, and a week for Christmas when it melted after a heavy rain. If you use it, be certain it is under cover and cannot get wet.I think this unit is better than the one I had been using for about 10 years. It's not hard to set. Works perfectly.Very hard to find these anymore. They are simple to use and not much on them to break!why bother having a timer if it never works. Ridiculous and waste of time having to ship it back to the seller. Spend 3 more dollars and buy something worth it.Still working, didn't stop when the temps reached zero F.Simple setup. Durable. And small enough to fit in small areas.
