Pros and cons

Pros

Editable text, patterns and animations give the display more uses than a fixed message sign.
App control includes brightness and speed adjustments, and the listing says multiple displays can be connected at the same time.
The compact, flexible format is intended for window mounting and can be rolled for storage.

Cons

The listed display area is about 34.8 × 10.2 cm, so it offers less sign space than a larger window display.

What to know before buying

The listing uses both plastic and flexible PU and FPCB material descriptions, and its stated dimensions appear in more than one format. It also describes both a 5V/2A input and charging through a 5V/2A vehicle USB interface. Confirm the material, exact size, power connection and intended mounting position in the selected listing before buying. The waterproof rating and visibility claims are manufacturer statements, not independently established here.
