Functionality: a. Lot of ways you can use these signs. Also they are programmable easily. You can easily to customize them.Usse emoji’s and different colors.A+++ 😃✅

This sign is so much fun in the back of my car. I let the kids run the remote control it comes with to play the preset animations or I can use my phone to play any of the hundreds of downloadable animations that are in the free iOS/Android app. I can even make my own animations and text messages to play on the sign.For power it comes with a USB power adapter for a car's aux power port. The sign then comes with a super long power cord to read easily from the front of my car to the back. This is a lot of fun on long trips with family.

I had the holiday lights swinging in my car over the holidays, and now it is time to choose from the tons of pre-made animated programs for the new year!They have their own app for your iPhone or Android to download from each app store.It is super easy to change programs and there are a lot to choose from too! Also you can easily connect your Apple Music (or Android Music) so your program will move to the rhythm of the music, or even from your voice if you set it to the "Mic" option!You can even make your own programs, something I will do very soon!The panel comes with a 12V plug-in module for your car's power plug or cigarette lighter to convert the power to USB-A and also a very sticky thin tape to mount the panel on your car's window or elsewhere.This LED Matrix Panel is a lot of fun and you can express your different moods with it. I love it!

We love it in this house, we are able to make it look like F1 drivers on the screen with their little tags. We do have a lot of fun with it lolsuper simple to set up, you do need an app but it's a fun thing to mess with.

I ordered this to use for my office entry window at work. It's a decent size and very bright. It came with the display, car accessory USB power adapter, double-stick tape, and an almost fifteen foot USB cable.Everything is provided to hook up the display in a car and get started using it. Only a device with the app installed is needed to connect to it with Bluetooth to setup the display. Once connected with the app, there are various pre-made graphics and animations that can be used. An image can be uploaded to use, but the resolution is limited to how it converts to use it for the available pixels on the display. I've found that it's best to use an image that is very simple, bold, and has good definition or difference between colors and shades.Besides that, the app is very limited to what it has already pre-made. There are quite a few images, but many are emotes or variations of one thing or another. Some aren't useful for a business or professional environment. Using an iPhone, I haven't found a way to import video or GIF animations directly to the app. I have a smaller display that uses the same application (CoolLED 1248) and has quite a few more pre-made images and animations, especially for the holidays. Because of this, I think what images or animations are available is based on the dimensions of the LED display.I've powered the display with the car USB accessory adapter, a power bank, but it is connected mostly with a small and cheap cell phone USB power adapter.The app is very consistent in connecting, uploading, and changing displays, so I am happy about that. It's also very easy to setup scrolling text, draw out your own image and animations by pixel. They can be added, in any specific order you choose, and uploaded to the display. Once they are uploaded, you just need to turn on the display. They can be set to auto-play or you can use the button on the cable to move from one image to the next. When the display is powered on, it will retain whatever images were uploaded to it. I haven't had to re-connect to it or open the app but to only edit or add to the images.The cable has an inline power switch built in. There's also a "next" button near where the cable connects to the display to change to the next image, which makes it easy to setup an Open/Lunch/Closed cycle without having to open the app. Those two things are a big convenience for me since I am always in and out of the room.It's a nice display. The size is good for text, especially scrolling, and it has an okay selection of pre-made images and animations. Color reproduction is also okay. It seems to be only limited by the application, but I am still happy and manage just fine with it. I've been using the display with the app for almost two months now and it has been working really well. For the price, this display is on the more expensive side, so I don't think it is the best value unless you can get it while on sale. What does offset the price compared to others is that it includes such a long USB cable with both an inline power switch, a "next image" button, and a USB accessory adapter for the car.

I can’t believe how lucked out with this sign! That said, I do think the app it uses could use some improvements. I often find myself feeling overwhelmed by its features and wish there were clearer prompts and explanations to guide me. It seems like it will take me quite a while to fully grasp everything but I'm pretty determined to figure it out.I checked the app reviews and noticed that the creator is quite receptive to feedback, which gives me hope for upcoming updates and enhancements. I also stumbled upon a Reddit community where users can share their designs, which sounds fantastic! While the app does offer a decent selection, some are not really my cup of tea with their design so having the ability to exchange ideas with others would greatly expand our creative options.As for the display sign itself, I’m a bit anxious about how the connection is made. It seems to rely solely on soldered parts and wires, which are only covered with plastic. Considering I plan to use it outdoors in colder conditions, I'm concerned that the plastic could become brittle and that I might accidentally damage it. I really hope that doesn’t happen.On a brighter note, I think it’s awesome that you can upload your own photos through the app. While it does warn that the images may come out grainy, I’ve found that they still appear pretty sharp from a distance, and up close, they’re quite distinguishable in my opinion. Overall, I’m excited about the potential of this sign and its app!
