I bought 3. The product is great but they are old (2006) and all came with dead batteries. The batteries are 3 volt CR2 and expensive. With new batteries they functioned well.

Works well. Easy to install. I like the manual override so I can turn the light on/off early but still have the timer. I was disappointed that the battery it shipped with was dead. This caused problems with the device setup...because the device displays the time but won't allow you to go into setup mode when the battery is low. Once I finally guessed that the battery was almost dead and ran to the store for a new battery the setup went just fine. I would like this device even better if the it could hook into the house AC power and use the battery as a backup power source. Hopefully the battery lasts a long time...because I don't like changing batteries on devices that are made to be set it and forget it.

Certain batches of this timer switch were RECALLED in 2009 by Intermatic. Our unit quit after working perfectly for 4 months. I will not be replacing this switch with another one since as one of the other reviewers so correctly commented, it's battery driven. The controls are battery operated. When the relatively expensive CR2 battery dies the unit does not work. As you can probably imagine, you also loose your programmed settings. You see many 5-star ratings from others, and that's what I would have thought for the first four months that I owned this unit, but not anymore. I would avoid this battery-operated switch or be prepared to infrequently replace batteries and re-program this unit. My local Home Depot stopped selling Intermatic timer switches after the 2009 recall problem. This is likely a model to be avoided.

As far as what it does, it is excellent and the quality is very good. I just wish programming such a little device were a simpler when setting individual days and times.

More reliable than the X-10 product that it replaced.

This switch is perfect for applications quiring variable programming times. One note: You have to be careful when programming. Wach program correcsponds to one on/off time NOT one pair of on/off times. Trivial but Ive been bit in the butt more than once.

This is the second switch I've installed without any problems.

Thanks Smarthome for your 2509A 7-Day timer switch it worked excellent and your delivery time was excellent thank you again! i am looking forward of doing more business with you guys.

Uses a non-rechargeable, expensive battery for the control circuit. Battery does not last long (a few months), and when it fails, the circuit is no longer controlled. First Leviton control that ever disappointed me.

It works as advertized
