Query: Great timer!

Great timer! I needed something to use an both a timer and an alarm. This has a 19 hour timer with loud alarm as well as a vibrator and light. You can turn each one on and off as you like. It has a clip you can use as a belt clip or clip it to something in the area you need it. It also has a magnet on the back of the clip. It takes batteries and they last quite a long time. All in all a good time and great price!
