Works fine for me
Color: Style A：Pink
Everything worked as it should really happy with the fact that it came with a few sticky back tie downs to help keep the cable from swinging around. I'm hoping this one will last longer than my last one. ( Purchased from a different distributor.)

It works, but wiring is bad
Color: Style A：Pink
It works, but is just another one that is an exposed main board that lights up. Edit: it recently had a wiring issue. I will have to buy another kind. These aren't working for me at all.
