RAYHOME Scrolling Bright Advertising LED Signs, Flexible USB 5V LED Car Sign Bluetooth App Control Custom Text Pattern Animation Programmable Display for Store Car Bar Hotel (15''x4'')

The best led matrix ive had works well

I really liked it. It works great and is easy to use. The best part is that it's perfectly compatible with Uber and Lyft, which is very convenient for drivers. Good quality and meets my expectations. I recommend it.

Lightweight, very bright, and works exactly as advertised.

put this in my car window as a joke and people actually read it and react at red lights. takes a few minutes to figure out the app but once you get it the text is easy to update. bright enough to see during the day which I was not expecting.

This thing is kind of fun. I use it outside of my home office to let my family know when it's safe to enter or when I'm in a meeting and they shouldn't enter. So far the only thing I've noticed is it disconnects from my phone randomly and I have to close the app down a couple of times to get to reconnect. But otherwise I love the preloaded options it comes with and I like that I can create my own. I wanted a digital sign that I could use with my phone so that I don't have to get up from my desk and flip it over. I feel like I would forget to do that everytime. But with this sign I can change it right from my desk and it conveys the message outside my door without me having to move, it especially helps if I'm busy right up until a meeting, I can log into my meeting and quickly change the while I'm listening to other people on the call. My family thinks it's hilarious to read the random messages I come up with. I've only used it for the last 4 days so I can't comment on the longevity of it just yet. But hopefully it'll last quite a while.
