Worked great and easy. Made for a great gift, very happy with it, thank you!

Awesome 😎.

TLDR: works as advertised, great sellerWant to give the seller mad props, for one. They are super-concerned that you're satisified with yourpurchase, 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.

Great little device and exactly as advertised. Easy installation and 100 percent great for my side gig.

Bright, and has brightness adjust. Plenty of fun options and quite customizable. Easy to set up and be up and running within 10 minutes. nice!

My dad had dementia and kept asking what day it is and what's going on. He would forget as soon as you tell him so each morning I would get up and put a new date, day and message on there about what nurse was coming etc. I put it right under the TV set where he was watching games shows, and baseball. I put it on scroll and it reminded him what was going on and he didn't have to ask nearly as much. Caveat: don't forget to change the message or you will cause more confusion.

The LED is pretty cool, just what I want. The led are pretty bright with the option to dim them. The display size is good but I wish the parallel row has more LED only 16 and it’s hard to draw on 16 pixels.I’m not sure if it is the LED or the app, but they is Only 7 colors to choose. more colors is definitely need it.Cons: More LED/Pixels on the display, terrible app, no option to copy and paste, no option to import/export gif. No undo option. Only 7 colors and no option for color pick. When using app to draw if zooming or un-zooming using two fingers the pixels get mess up.Pros: the display is pretty neat and bright. Easy to install, can bend with not problem. Attached usb cable pretty long with two switch to control LED and turn it On/Off.

Works great! Love that I can turn it off with a flick of the switch in the car and not have to open the app.If you don’t want to use the supplied tape it sticks fairly well just on its own. I’ve had it last days before falling off.
