This is a basic timer that performs its function adequately. Only criticism I have is that the clock timer mechanism can be a little too easily moved by an inadvertent movement when you are holding the unit.

No one broke into our house, so it must have done its job. We needed seom simple timers when we went on vacation and these were a great value and very simple to use. The "fuzzy" start/end timing was a nice feature, allowing the start and end time to vary a half-hour from the exact time marked on the dial, to throw off burglars who might be watching the house.

This is a great timer. It turns things on and off, which is what timers like this are supposed to do. It's not accurate down the time minute, but is close enough, if you are turning lights on around the time when it gets dark outside or using it for security purposed, when very accurate timing might actually give away the fact that your lights are on a timer.

The only downside I have with this timer is a light "clicking" noise, which sounds like the timing mechanism or something within the timer. Everything still works, but it's not exactly "whisper quiet."

If you are using this in a situation where you need total silence, such as a bedroom you are sleeping in, you might want to look at a non-mechanical timer.
