LED Slippers are useful. When we walk at night at home, the light from the slippers can help us see the way. It’s safe and convenient.
Two-way Glasses are useful. Maybe when we want to look at something far and also read something near, these glasses can help. It’s easy to use for different needs.
I think the Noodle Fan is the most useful. When we eat hot noodles, the fan can cool the noodles quickly. Then we can eat the noodles soon and not burn our mouths. It’s very convenient for eating noodles.
