LED Car Sign, Programmable LED Matrix Panel FPCB Flexible Screen Display Animation Message Scrolling Sign APP Control for Cars, Shop, Bar, Party Festival 14.6"x3.6"

The VDIKKS LED Programmable flexible sign is an excellent product! I installed it in a Tesla Model Y. I really liked the sizing and the customizability. I ordered the 27 x 5 inch version. It was able to fit in the area I wanted of the rear window. The LED matrix is very durable. The adhesive included is extremely sticky and holds the sign up in the window vertically despite the Texas summer heat of 90 plus degrees Fahrenheit.The flexibility of the sign allowed it to curve with the window and not be to difficult to install. The rear window is heavily tinted but the brightness level at 220 allows the LEDs to be seen at night. In the daytime turning it up to maximum brightness requires the viewer to be directly behind to see it due to the heavy tinting. If there wasn’t any tinting, then the LEDs would be clearly visible in the day.The customization options make it easy and fun to use the sign with the app. The included charger cigarette lighter outlet plugin. It lights up blue showing there is power being delivered through the outlet. There was plenty of cord length to reach the outlet. Customizations include being able to have a long line of text, changing the display speed, duration of stay, borders, font size, rotation, bold, and coloring.A particular program could be saved via the app and then uploaded whenever desired to the LED projector. Changes could be seen immediately. There was even a catalog that could be gotten through the discover store or material folder. These could be uploaded and changed on the fly when accessing the app.The screen could be flipped on the x and y axis. Brightness is adjustable up to 255.Excellent value for the money!

I didn't expect a lot but was pleasantly surprised. I needed an office door status sign for my home office to stop the fam fron barging in on video meetings that were being recorded. I don't know why it took me three years to even look for this product, but here we are. I only used it in my home. I'm sure it would be awesome for automotive usePROS:This thing is pretty basic in looks, but does the job. Its a thin, flexible sheet of LEDs. The app is actually pretty useful. You can do a LOT right out of the box, but I ended up creating several of my own custom graffitis.It's BRIGHT. I use it indoors so I turned the brightness all the way down.The cord is super long so it's easy to position and still have enough to reach a power outlet.The Bluetooth connection is solid. Not a huge amout of range, but solid within 12-15 ft. It's also a thin and flat enough cord to be able to mount it through my door frame without damaging it.CONS:Mostly to do with the app. I wish I could shrink or modify the text to put two lines of text on a single frame, or even more than four letters on a single frame. I was trying to write ON AIR and just the five letters and one space made it break across two screens. I get that it's optimized for LYFT and UBER, but it could be more useful with text size options

Received the product well packaged, came with thorough instructions on how to set up and how to get the app to control it for the phone. Very lengthy cabling to allow for mounting anywhere in my vehicle. Pretty easy to set up and synced with my phone flawlessly.I primarily purchase this to add a little more personal flair to my vehicle as an Uber driver. Only found 2 areas of improvement that I have communicated to the seller:-Firstly, the supplied adhesive is a roll of very thin, foam type double stick tape. The adhesive on it is not very strong. I initially intended to mount the sign on the top corner of my windshield, but the adhesive did not want to stick to my window tint, even after pressing firmly against it for some time. I ended up mounting it on the bottom corner of my windshield instead, directly against the glass. Had to hold it firmly down on the glass for a few minutes just to make sure it stayed in place. I'm only concerned that with how poorly it adhered to the window tint, that being near my defroster vent where it's subject to change in temperature and condensation may form, that the adhesive may give out sooner than later. I do plan on buying a better quality adhesive to mount it where I want to, but it's been on there a week pretty well. I'll also note that the supplied tape does not stick to the two plastic control housings (on/off and pattern-toggle) at all, so I was unable to mount them in conveniently located positions and they are just currently sitting atop my dashboard and on the floor next to my passenger seat, but that's okay because the software can change the pattern on the fly, and I have a toggled outlet that the sign is plugged into.-My other concern is the Control software. It's very easy to use and simple to understand. I was under the impression that the sign would do a better job of emulating emojis, even simple ones like hand gestures (think waving or peace sign) but it seems to be limited in its ability to convert a lot of emojis to an image on the sign, instead just leaving a random symbol or nothing at all in those spaces, but displaying numbers, letters, and punctuation with no issue. I like the ability to individually change the display colors of the lettering. And there is a graffiti feature that allows you to draw your own designs, but I'm neither creative nor patient enough to do that. It would be nice to see some sort of community design-share within the software for people to share and download designs, but one step at a time.All in all, I think it's a good product. Could just use a little tweaking from the software development end of things.

I loved it, you can put the poster you want on App

It worked amazing, but it broke within a few months of owning it. It was readable. The look was great. It was doable. The quality was good and it was easy to use.

Got this for my friends party bus! The price was right! It totally was easy to install, stuck to the window with ease and looked awesome! It’s made with strong soft materials

The adhesive that this product had is trash and it won't mout for anything it just falls. Looks ok when lights up the message quality is good but we had to use other methods for sticking it up
