Lin Tang explained, "It contains a battery, and one battery can last at least several months. If the battery runs out, just replace it and it could continue to be used."
In short, as long as it wasn't smashed heavily, this thing could last a very long time.
The Lin Family had a radio, which also used batteries, so they quickly understood.
"...This thing is pretty convenient," Zhou Mei was once again impressed.
She nudged Lin Qingshui, who was watching intently, and whispered, "Zhiming's dad, do you want a flashlight?
How about we save up and buy one for you?
If you have a flashlight, you can see the road clearly when you come home from night shifts."
Lin Qingshui firmly rejected the idea.
"No need! This thing looks expensive at first glance, we don't have industry coupons, saving for this is not as good as making clothes for you and the girl."
Zhou Mei was touched.
Before she could speak, Lin Zhiming, with his dark little face, said naively, "Dad, you forgot about me."
