Question: How do you turn the timer off to save the battery?
Document: This dual timer has flashing green and red lights (you can turn them off) to alert you. It has countdown and count up functionality. It is not a clock, however, unlike some other timers.
I got this timer for studying - and it's got a very bright green light that you can't turn off. if you're purchasing this for timing you during tests, as I am, it is way too distracting.
The timer was shipped promptly. I used it during the bar exam. Both the count down and count up was useful in keeping track of the remaining time left for each question and remaining time for the entire examination. I had to tape the flashing light to avoid the distraction. The extra large display is good for a quick glance. The manufacturers should provide a switch to turn off the flashing light. Will certainly recommend the product.
I love this little time with its dual timers. We keep one fixed for my husband to use daily when riding his exercise bike. The other I have can set for cooking without having to wipe his setting. I like it also has a beep that does not stop it beeps for a while till we turn it off, it may stop but have let it go that long.
looker around for some time and this is the best dual timer foundReally easy to use and magnetic too
I was looking for a dual timer that could count up or down, this does just that. I have only used it once so far, but it does exactly what I wanted it to do. thank you.
Does everything a timer should do..........counts up after time out, has audio and visual alarms, and can be programmed for a long time range, Dual timer are great
Great timer! I like the flashing green light because I may forget I start a count down! Very good product!
1/2". not enough to keep the unit upright when pushing buttons. I had to add a flap of cardboard to make it stand at a usable angle. This is the best timer/countup unit out there.
I love this digital timer. I've tried several others and this is by far the best one. It is easy to use and read. I even bought one for my mother-in-law and she loves it, too.
