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

This LED sign is flexible and can be stored rolled up. So it also contours around posts, curved displays, etc. Easy to read in light or dark. I'm using it for a photo booth to advertise the hours. The base for the booth is metal, so I attached a couple of medium binder clips to strong magnets. I clip these to the ends of the sign and use the magnets to attach them to the side of the base. Highly visible from even 100 feet away.It can be powered from a USB battery pack, making it 100% portable. It also includes a car lighter adapter. The cable is around 15 feet long and has a button that controls orientation and modes (scroll, slide, etc.)For full control you need the app. The app is decent, but sometimes not intuitive. A check means "yes" in some places and cancel in others. The animation thumbnails don't match the actual animation for about 1/3rd of the animations. You can't use your own animated GIF or import images. That's a disappointment. Text editing is powerful and has a LOT of options. The colorize screen was bizarre at first. I had a 30 letter sentence. The screen just took the letters and spaced them out on the screen. At first I thought it was random text and a bug. I sent several minutes customizing colors and hit the "check." Well, on this page, check means cancel.The manufacturer responded to my complaints on the app page saying that they would be corrected in the next app update. Hopefully they will, because the app is the weak link. For text, stock cartoons, flags and animations, it's great. Making your own animations? Way too tedious.

These signs are amazing! So easy to set up and use. Bright and bold, they get peoples' attention, as they're designed to do.We use them all day, every day, in a business setting. No problems at all.

Amazing! Works great!
