    Bullet proof - simple - reliable - Great design from a great company
  

*by J***N on Reviewed in the United States on 16 December 2017*

Works great with all kinds of lightbulbs – I tried a couple of others and did not have good results with my LED lightbulbs. Intermatic is the original best mechanical timer – this heritage of using a mechanical type off/on (this switch “clicks” when the internal control goes from on to off) is the reason this timer works with all kinds of bulbs. Unlike some electronic timers – when the Intermatic switches to off the circuit is totally dead. Plus does not need a neutral wire – many older homes like mine do not have a neutral at the switch wiring - so  can be used for almost any application. Switches which require a neutral do so because they are using some of the power to operate to switch program -  instead this uses an internal lithium battery.The astronomic feature is terrific - it adjusts the dusk and dawn time based on your generic location. Programming is easy – watch the company YouTube. You can program each day or program for “all” days. Then it is just a matter of setting event 1 - which is when you want the switch to turn on - event 2 is when you want thw switch to turn off. In my case I chose on at dusk and off at dawn for some outside lights. Scrolling through the menu is just a matter of hitting the on/off switch .Some revieww comment about the battery – this is a good feature because the battery maintains the programming – if the power goes off the switch still has the programming.  The battery is a great advantage and part of the design because this timer switch makes the circuit absolutely dead and does not use the house power to keep the switch programming.  I have not had the switch long enough to have a battery go out – the lithium battery should last several years and another great feature is that when the battery is getting weak the switch gives you a low battery warning. Battery replacement is simple from the front cover without removing the switch on the wall. When you do change the battery you do not lose the programming because it has internal memory for a few minutes without a battery installedAnother great part of the design is that pressing the cover changes the switch from automatic to manual to random. So you do not have to flip the cover open to get at the small program buttons to make a simple and more frequent choice – for example when I’m gone I click it to random for a couple of rooms - The timer then varies the preset times - For example rather than going on at 9 o’clock it might not turn on until 915 and instead of going off at the set time of 1100 - It might switch off at 10:45 - so it has more of a somebody is home look.The switches are simple you set it and forget it – the wireless/hub type switches are usually a problem for older homes which just have the hot wire and load wire at the switchbox without a neutral and/or ground . Plus when it comes to appropriate technology – I really don’t want to get on my phone and go through an app and play around with lights all the time LOL.I now have four of these in my home -  hope they are like my last Intermatic mechanical timer switch - It worked every day for 40 years - This is a brand which I trust. So I totally recommend these timer switches.

    Easy to program, looks good.
  

*by D***L on Reviewed in Canada on 27 April 2017*

Works great so far. Easy to set timer if you have ever set a plug in electronic wall timer. Piece of cake, but take notice the 7 day program starts on Monday.  Wiring in was a different issue. As I only had a 2 pole light switch, the instruction were not very accurate to hook this up. I went on internet & found a sight on how to wire wall timers. It actually listed this brand as well. They were step by step clearer. Followed that & bingo, works perfect. It was just a matter of having red wire going to correct wire from wall. Love the random on/off setting for better security. Found same product at local hardware store but at a higher cost.

Does what it is supposed to - I like the timer for lights. Had a bit of difficulty getting it set up at first but it has been great so far - have had it about a month.
