Customizable Gelrova LED Display, Flexible LED Car Sign Light Remote and App Control Custom Programmable LED Display for Store Car Bar Hotel, Scrolling Bright Advertising LED Signs (14"x4")

I turn this on when I go for my night drives, and I always put funner things on, you can write or draw whatever you want. It’s definitely a good deal nice quality, was hesitant on how sticky it was because I’m in Florida with tinted windows and they get scorching hot during the summer, just make sure you clean the window very very well before putting it on. Mine has not come off and it’s been on there since February 19, it’s now May 7. 10/10 would recommend.

This little thing is pretty cool. It comes with a remote that has a bunch of presets on it that you can use right out of the box. You can also get an app on your phone for this - The app has a ton of other signs and whatnot that you can use with it by simply downloading them. You also have the ability to make your own signs / messages. You can make them in different colors, fonts, use emojis, etc.My only concern with this is the legality of using it for it's intended purpose. I haven't been able to find anything that actually says if it's legal in my state, so for now I'm not using it in my vehicle. But it does work, it lights up bright and is a funny little novelty piece. 4 star overall from me!

The messages were pretty clear

Amazing

The only thought I have is I would like it longerYou must write things too short.How about a 28" long one.Send one to me I will test it for you.

A fun, slightly-quirky customizable display with slight learning curve that is worth the time and effort.For this size I ordered (larger), the near-$50 price point seems fair, but in honesty, I would watch for it to drop likely into the sub $40s during the soon upcoming sales blitzes, and would recommend trying to get one at that point, if able to time it right.There are GOBS of variants of these displays, so it's difficult to recommend one over the other. but this one does seem to deliver on its promises, and nestles in with its pricing quite-well.

The media could not be loaded. I wish I could post the video that I made while I hit the remote for the first time. The display can be rather, how you say, "In your face" with its frank, yet bold, programmed sentiment. The opening scene from "Branded* with Chuck Connors comes to mind when I consider the consequences of posting such a video. For that matter, the consequences of flashing some of those messages from a car window are perhaps not inconsiderable. I remember the great Twentieth Century advertising signs in big cities with all kinds of moving graphics in lights. This unit reminds me of those, and since well before I was permitted to drive, I have wished there were such a thing for the rear window of my car. This appears to be exactly it, and before I'm dead too, not a bad deal. And not only can one insult seventeen generations of somebody's family with this, you can say nice things to people, or make a pass at someone! Tastefully of course...This thing is fun. There is a foldout sheet of instructions that I tried several times to read; I kept having trouble reading it, due to the small letters and choice of colors, so I just plugged the device in, and it responded quite nicely to the remote. I made better progress with a magnifying glass, and then downloaded their new app, not necessary for using the unit, but it will be easier for me to read. I am particularly interested in customizing some messages; I don't often wish to tell people where to go anymore, though informing someone they drive like a cabbage might be warranted in certain situations.This is a worthwhile device. It seems a bit delicate--I am unused to naked yet flexible printed circuit boards--but if it lasts two years, it could be worth it, especially if one is doomed to perennial rush hour entrapment on the freeway by by the banal and merciless hordes.

Do not use in hot days! Mine fell off my trunk window on a hot day.

I just open box , and connect screen with USB power . Not Working
