This LED sign is a huge improvement over my last LED sign in many ways. But there are still a few areas for improvement. * This sign is slightly taller than my last sign. * The app is pretty easy to use. You can select from text, template, or preloaded content. I made the signs in the video in the Text area of the app. You can select text, color and size. But you can not choose the font. I dislike how the U in Uber looks on the sign. I am hoping for an app update that will make the U look more like a U and less like a V. * The app has settings to control, whether the text stays still, or scrolls in a few different directions. I prefer the left scroll. It has a speed control for the scrolling, but I wish there were more slower settings options. There is very little difference in speed from speed 1 to speed 5. The lowest setting still scrolls way too fast in my opinion. * This sign has a unique option to display two lines of text at the same time. But it doesn't allow you to center the text on the screen when in static mode. This is super useful for long gig names like Uber Eats, Doordash, or Instacart. * You can easily switch between the different signs in the app. The app has many design options. But it still doesn't have the option to load graphics directly from the Gig companies. Also, on the main program screen where it shows a list of your sign designs, it has an issue with the the color orange. For some reason, it shows up as red, when the design is orange. Luckily when you load the orange design to the sign, shows up correctly. * This sign made a huge improvement by offering an on-and-off hard switch. With my last sign, I had to buy an aftermarket on/off switch, because the push button only turns the sign off, for one car ride. So you will find yourself having to turn off the sign all the time. (Like when picking your kids up from school or going food shopping.) It was annoying. So I am glad they upgrade this model with an actual on/off switch. * It comes with a 12-volt 2 USB port adaptor. It is USB 2.4A and 1.0A. * This sign is designed to be held to glass with a roll of gel tape, that is sticker and more reliable than other options out there. (Included). This is an improvement over other signs that have weird "reusable" sticky pads to hold the sign in place. They didn't work that great and my sign kept falling while I was far from home Ubering. I had to buy after-market tape for my old sign. This design upgrade will make my life easier! * The power cord for this sign is nice and long. You should have zero problems winding the wire around your car to a USB port. However, the cord on the side that plugs into the sign has a weird type of port that I can't identify. I don't think it would be easy to find an aftermarket replacement if this cord is ever damaged, or lost or if you need a much longer aftermarket cord for a van or a truck.

I ordered this sign as I thought it could be useful for driving gigs/jobs and I thought it might help avoid unnecessary complaints, tickets, or getting towed while a vehicle is left unattended for a few seconds, or minutes. The sign is a 24x48 RGB led matrix display, its a flexible pcb with a clear rubberized layer on top, the rubberized layer so far seems to stick to glass without additional adhesives, but the package also included a small roll of double sided vhb type adhesive if needed. For text you can set it to scroll or update your message across the screen, or for static text it can display 2 rows with a maximum of 6 letter words. You can use the app to upload your logos, images, or animations, although a lot of detail may be lost from the limited resolution. The app includes a selection of various images, and animations you can choose from. For my intended use, I need to restrict my use of the device to static text/images, not containing red/blue colors, flashing, or animations which may not be legal in most places. I may just turn it on when parked, but I like that it saves your messages to the device which are not lost when you turn it on/off, and after programming with your desired messages you don't need to keep it connected to your phone. You can set several messages and adjust the timing for those to be display before it automatically cycles through them, or you can press the button on the power cable and it will manually cycle through your sign messages and stay on the one you click to. You can also double click the button and it will flip the orientation of the sign upside down. The app is available and published in the google play store, and is fairly usable, although it does take some playing around with it to figure out how to use it. You can also set a security code for the sign that should block others from being able to change your display without knowing the code, which you should set yourself before someone else does it for you. Overall I think the sign will be useful for driving gigs, or for a good store front sign to display open, business hours, back in x minutes, etc.

Seller is marketing this item as usable in cars knowing that it would require an adapter that he will not provide.

I ordered "Double Row LED Light for Car" My review The double-row LED display is a fun and versatile way to add customizable messages to my car. The Bluetooth app control makes it easy to switch between different signs and settings. The hard on/off switch is a nice feature for quick control. One thing I appreciate is the gel tape mounting system, which holds the sign securely to glass and is more reliable than suction cups. The USB-powered cord is long enough for flexible placement. Overall, a great addition for personalizing displays or adding a fun touch to any car
