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 rotate to the bottom, then rotate back. If the ringing is not at 0 but at about 1 minutes, this is normal because it is mechanical. Within 3 minutes is normal. If you need very precise time, only electronic timers can be precise to the second. When you receive this product and during its use, please remember not to "anti-twist", because it is the "upper hair".Please pay attention!!!
