NENRENT DC 12V LED Car Showcase Sign Scrolling Message Display Board Led Car Rear Window Banner Lighting with Remote Controller and Car Lighter Fast Programmable (White)

This is an excellent quality product. I installed it in the back of my car. The message is for those aggressive drivers not to tailgate me.The seller reached out to me by email to know if everything went well, and that they have a one year warranty on the product, should I have any problems. I would say, this is the first time any seller reaching out to me at Amazon and I have used the site for more than 10 years!

Was looking for something to hang in the back window of my van, and this works. Just a matter of understanding the programming. Read the instructions.I did have to rely on the work-around by another reviewer of how to get rid of the default banner.Not having an actual power switch or a way to unplug from the unit itself was the biggest drawback. Otherwise, functional.

Plastic can't handle the heat when in the dashboard.

Overall good product. A little pricey, kinda hard to figure out how to save the message and only way to turn it off is to unplug it. But it's bright and does what it's made to do.
