Everything arrived in the promised time and excellent condition. It's great. I was delighted. The app by QR code downloads and installs on Xiaomi superbly (even in Russian). Sometimes there are depressions when switching modes, but as I understand it, they are still working on it. New features are added in the app, some (such as adding video) are there but writing is not yet available. Means the program is not abandoned and is constantly in development. It's great. The colors are juicy and bright. Brightness and speed are adjustable. There is protection from moisture. In general, everything is as in the description. I recommend to buy, you will not regret it. The seller is also good, sociable. I didn't regret buying it.

Purchased 7 times We used this scrolling LED sign at the STATE Robotics Competition above our PIT table (I made a base out of an old car disc brake and painted it black, then put a long dowel rod down the middle so the sign would be really high), you could see the sign from anywhere in the Stadium clearly (unless you were behind it, unfortunately it is the sign is only on 1 side). In fact, the judges and competition staff used this LED sign as a navigation point to direct people and services to different tables in the pit area! They told me it was very helpful to tell everyone, go 3 tables past and 2 to the right of the Lorena LED sign! We also had our school name repeated over and over... :) At first I thought it might be too small, but it is very bright and did the job, sorry the pictures don't show the scrolling, but the bright scrolling caught everyone's attention! Recommend!

Purchased 5 times Nice app controlled LED screen. In the app.. some really neat things you can do. For example, you have Text, Patter, Graffiti and Animation options. First the Text option. There are modes that you can have the text appear. In my video I use the button on the cable to flip thru the modes. The modes are: Left (scrolls left), Static (which flashes each section, if the words are longer than the screen), Laser (creates a lazer like effect as it paints the letters), Picture (pans out from center out), Snowflake (builds down from the top), Down (letters drop down), Up (letter flow up) and Right (scrolls in from right to left. Pattern. Has a ton of pre-made patterns of both dynamic and static versions. Christmas, Thanksgiving, Halloween, etc.. are in there. Graffiti is where you can make your own. You have a screen where you can use your finger to draw whatever. With options like fill, etc.. zoom out and in. and make colors - 7 colors. Animation is where you can take your Graffiti and animate it. Also, a Music setting. This is where you give the app access to your music and it creates the bars to play to the music. Was not as impressed as I wanted to be on this. As the bars were not tightly tied to the music. As you can start the music and it takes a few seconds for the bars to react.. then they are reacting a few seconds later. As I thought if this was more in sync, could easily see a DJ use for this to mount on the front of his tabletop. Each of these have to download to the device.. takes around 10 to 15 seconds.. then they play. Also comes with nice and sticky tape. You know this as it's tough to pull out of the plastic bag its in. You can use this to mount this rubber mat with LEDs inside to whatever. You could easily mount this to the inside of your car window, front or back. Another fun use of it would be to hook up the USB A port to a power bank, and you could put someone's name on it at the airport to make that really special welcome instead of the simple
