KJOY Large Bright LED Sign,37''x8'' Flexible 12V Multi Ttask Loop Playback LED Store Sign, Bluetooth App Control Custom Text Pattern Animation Scrolling LED Sign Programmable for Store Hotel School

Great value for the price. I like the brightness of the light and color. The sign quality and easy use of the app. No problem with installing.

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.

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

Have had it for a couple years, installed as an auto display, have never had an issue. Bright leds, still get compliments about been an enjoyable product

Awesome light! love this put it in my car to add some fun to my drive. I love this sign it is definitely worth the money and easy to use. So easy to read especially after dark. The quality of the sign itself is second to none very well made. It's easy to apply you just use the adhesive strip to stick it to the window and it stays.

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.

so far its okay
