KJOY Programmable Huge Bright LED Signs, 27''x5'' USB 5V, Bluetooth App Control Custom Text Pattern Animation, Scrolling, Flexible LED Display for Car Store Party Bar Hotel

WOW! I literally just put these in my car and ran into the house to write this review! These are amazing! So easy to install. I had them up and running exactly what I wanted within 10 minutes! I am blown away and ordering more as soon as I hit submit. The quality is wonderful and they are perfect! Getting more for vehicles and for our business windows.

TLDR: works as advertised, great seller Want to give the seller mad props, for one. They are super-concerned that you're satisified with your purchase, and I'm good with that. That being said, I'm quite satisfied. The thing works more or less straight out of the box. Download the app, do the bluetooth thing, and zip-zap-zowie, you're up and running. The tape that comes with it for mounting is sort of so-so, and it might be that my particular installation has something to do with it, so no points off. Your mileage will vary. I attached it to a stiff piece of cardboard, and the whole thing fits nicely in my back window. The USB adapter and cables that come with it are more than adequate to reach from a front-seat power socket to the rear, unless you're driving a bus or something. I also like the inline switch, if you need to go dark quickly. My particular installation, I power it from a USB battery-brick. The app is pretty straightforward and easy to use. There's a bunch of admittedly cute built-in animations, and a mechanism to create your own. I'd like to see some improvments to the app - when building animations, it would be nice to have the option to use the previous 'frame' as the starting point for the next. Also, some cut-and-paste functionaility. But it's a work in progress, so I'll hang out to see what comes down the pipe.

We bought this for our church and it working out great colorful and easy to use it gets the message across

Love this, nice and bright with many things you can do and edits through the app!!

This sign works as intended and looks great, but the adhesive tape that came with it is trash. I’d get my own adhesive tape on the side if you pick this sign up

Completely impractical and dangerous to use in any vehicle. First, it auto turns on every time you start the vehicle and displays whatever you last displayed. This can be problematic for obvious reasons. To turn it off, there's an inline physical switch that probably isn't near you and only a small button at the top of the app which is easy to miss. Then, you have to fumble (while driving) to select the images you want to display, choose the preferred order in their flawed queue system, and then send the data to the unit via Bluetooth (which takes a few moments every single time). This unit at least needs a physical remote control, which there isn't one available to purchase anywhere. Go buy a different unit. I will be.

Works great

This was purchased for my son’s Christmas gift. He loved the idea it just wasn’t big enough. I’m repurchasing this in a larger size.

Me gusto mucho, es facil de poner y de conectar.. yo lo tengo en mi cuarto y esta super bien.., lo unico es que el adesivo que viene incluido no es muy resistente

Works great so far I’ve had it for about 4 days I’ll leave another review if anything happens. It’s bright can be seen during the day just a bit dim in the sun, apps easy to use, was easy to set up, looking at ordering another for the driver side window as well

Easy to affix to my rear truck window with the supplied strong take which you apply to,it. I would reccomend that you plug it in first and find the proper orientation prior to affixing it to your vehicle window. I truly love its ease of use. It has a separate on of switch which you can affix near to you. And its use is so simple and so many visuals to use or use your own script.

facil de usar

It sticks to the window on it's own. Even in frigid weather. The display is bright and clear, though it can br tricky to get the correct direction for writing and arrows. Well worth the value, but now I want it to be longer. Buy the longer version if you want it for text. Otherwise, you can create speech or even pictures by drawing and writing as you see fit. As a first purchase test. This is great.
