Battery is one-time. Because shoe lights are vulnerable parts,
There is no guarantee how long it will be bright,
Someties the bumpy backlog in express transportation causes the battery to run out.
It’s not a quality issue.
Becaue he light is not on,
Because the light is on, theshoe does not have a USB interface. It is a battery on the sole of the shoe that sometimes causes no light over time. It is normal for one to be bright and one not to be bright, or one to be bright and one dark. If there is a lighting problem, for example, the left and right brightness are different, the leftnd right light will be bright and the other will not be bright, and the color will not be balanced. We don't deal with quality problems. If you mind, take it carefully! !
