Led Sign, Bluetooth App Programmable Led Car Sign, USB 5V Scrolling Message Led Matrix Panel, Custom Digital Display Board for Shop Advertising

It does exactly what it says. It's been stuck to my back window through the summer in Arizona and hasn't fallen off once! Super easy to install, just cut the sticky part and stick it to the Sign then line it up and stick it where you want it. It's bright enough that you can see the lighter colors through the tint. Definitely check your local laws, I use mine while driving and have never been pulled over. I have the little twinkling border lights changing colors with my business information and it's perfect!

Happy with the app and product. I’m actually surprised by this product. Despite what others said about the app I found it pretty straight forward and easy to figure out. You have a lot of options for customization, you can draw your own design to make a single frame gif or multiple frames, or if you want to keep it easy you can just type in the text and it’s that easy. When making your own multi frame gif you can spend a lot of time on it but it’s not required…if you want your message posted fast just use the text display and probably not the gif or animations.

Worked and looked great, everything came with it for you to install and use it. You can write a text to display on the LED screen using an app on your mobile device. Lots of designs and phrases to choose from or like I mentioned go free style. Super easy to install and affordable. It came with high end rubber tape, The only thing is for people living here in Arizona I’d use something different only because that tape here would not hold. The tape it comes with will not damage the inside of the vehicle it just wouldn’t take the Arizona heat!

Purchased to put on equipment in a machine shop to identify active jobs being run. Though it does the job, I only wish it had the ability to scale the text height so I didn't have to use the scrolling marquee feature in order to see all of the information which was just a few characters short for the 12" length of display. The adhesive tape works fine, just remember to clean the surface it is mounting on with some alcohol or degreasing agent as I apparently didn't do a good enough job on my first attempt to mount it. Thankfully, they give you an extra bit of tape The flexible surface wasn't needed for my application but I do like it in case I would have to put one on a piece of equipment with a not so flat surface. The unit does seem well made and the app was easy enough to figure out with not much experience with this type of device. I could change the sign information from more than 30' away which was also a nice feature. It has helped our production staff identify active work on the various pieces of equipment throughout the facility. We will certainly be buying more.

Loved this item at first but quickly changed my mind. The sign appeared and felt to be good quality except for the connection ribbon which was always flimsy. After only about 60 days the sign has completely quit working When it worked it was very bright and well lighted and I loved. While the app is not great it was adequate for my use as a door dash driver and Uber driver and I even had numerous compliments from other drivers However due to the fact it has completely failed I would not recommend it for purchase.

it works well and the price was right. I've been using it for a month or two and it has no problems. The software was not entirely intuitive, but it's not too hard to use one handed once I figured it out. The various different pre-programmed messages were a nice touch. Thank you!

I’ve had fun with this. I used it to announce my grandbaby is a boy to my family as they walked in the house. I used it to let the trick-or-treaters know when I was home and ready for them. I used it as holiday decor. It’s definitely worth it!

Edit: a couple weeks later it died completely. Not worth the effort. This was easy to setup and put in the truck. Its probably only run about 50-60 hours a month. No issues with adhesion or programming the sign... though I have my doubts about how well written, secure or privacy concerned the actual phone app is. That said, it has dimmed significantly and the white color has shifted to a pink and the colored letters bow have a band of different color in them. I would try someone else's sign first. I would not buy this again.

Very nice product gives you more confidence in expressing your thoughts.
