About KSM UP Sand Timer 6 Colors Hourglass 1/3/5/10/15/30 Minutes Sandglass Timer Sand Clock
Overall Feedback:
88% positive
87% were impressed with the accuracy, but 13% weren't
Timers are accurate within 10-30 seconds for different time durations.
I found the timer to be more accurate than the manufacturer's claim of +/- 10% of the indicated time.
Half of the timer set was inaccurate by up to six minutes. I returned the first set for a replacement and three timers in the second set of timers was also inaccurate by up to two minutes. I cannot recommend these timers if someone is looking for accuracy.
I timed the device and found that the largest error was in the 30 minute timer, which was off by -5.8%.
The timers are short by a certain number of seconds for each time duration.
The timers are not accurate time-wise. Specific information was provided about them going over or under by a certain amount of time.
91% appreciated the long battery life, though 9% didn't
I tried different battery-powered clocks but they did not work well. However, the hourglass timers worked great.
I like that I can give myself 10 minutes (or 15, 5, or 30) to work on a task silently.
Even after being dropped and played with by a toddler, the timer has not broken.
I checked the timer's battery life and found that the actual time for each interval differed from the intended time. I checked them individually multiple times.
I gave it 4 stars for accuracy because it ticks for another 40 seconds after it gets to zero.
