Dear, mechanical timers may have an error of 1-3 minutes, so if you need precise timing, we suggest you buy electronic timers.

Attention: Rotate the timer clockwise to the zero mark, then counterclockwise to the desired time. The timer will emit a clear ring when the time is up. That is, you need to turn it to the bottom first, then turn back. If it doesn't ring at 0, but at about 1 minutes, this is normal because it's mechanical. Within 3 minutes is normal. If you need very precise time, only electronic timers can be precise to the second. This product, when you receive it and during use, please remember not to "turn the other way," as it is wound. Please pay attention!!!
