Why do I hear a shaky noise on my pen?Updated 9 months ago
You may have heard recent news stories about exploding batteries. This happens as a result of overheating and is exacerbated when there is insufficient room surrounding a lithium-ion battery.
To avoid this issue, the iSpyPen Pro incorporates the battery inside of your device. If you hear a slight shaking noise, this is normal. This is the battery in your pen and it is not a sign of any defect.
