14'' x 4'' Scrolling Bright Advertising LED Signs [20 x 64 Upgraded Led Beads] [High Refresh Rate Screen], Flexible LED Matrix Panel 5.0 Bluetooth Control DIY Programmable Led Sign, Black

It looks like Apple blocked some Bluetooth functionally in iOS devices, like SPP. You have to connect to the sign from within the '+' button in the app, not in the OS Bluetooth settings. After that it works great.

Very disappointed with the quality, it losses its stickiness within an hour. The preconfigured options are boring and mostly useless. If you choose to create your own message that is more than one word the scrolling takes forever. If you want to use this as an open/closed sign that’s about all it’s good for.

The media could not be loaded. Overall is good. I can use both remote controller and my phone to control the LED. Actually I use the remote more than my phone because I use my phone as GPS while driving. The remote does not have “favorite” button so i have to pick my phone to do that which is not convenient (the app does not have “favorite” button as well). BTW some other similar products provide car charge adapter but this one does not. I have to purchase myself.Not sure if the code is open-sourced. If yes, I’d like to contribute and work with other funs to make the app better.Overall it is pretty good. May be my expectation is little bit higher. :)

I used it for few days the sticky they give you didn’t stick to my windows so it’s just in the trunk now not getting used

Bit bummed will probably return didn’t come with the remote!

Purchased and love using it

Would post a photo/video and review....however the thing never showed up. Looked like it would be cool....if ya ever receive it. Says it was delivered, however was not. They happily took my money though. No way to file any complaint, or for re-ship or refund.

In general is a good product.
