Got this sign for my wife's business and it works great for a text sign. The LEDs are very bright and can be read in the daytime with no issue whatsoever. The long USB cord makes it easy to locate about anywhere even on big windows. The colors were nice and vibrant. Feels very sturdy and sealed so the gulf coast humidity shouldn't affect it.You can store lots of animations and they run very smooth. No pauses or stutters.It took a little while to really make use of the app to display things, but it was fairly easy to get the text animations. Getting a picture or movie is much more difficult due to the low resolution. The video I tried to show was impossible to see without going through other software to reduce the resolution.Only negative is that the pictures in the description make it look like the resolution is higher than it is. The description says 20 x 96, but the spacing between the individual LEDs is large enough that you need be pretty far away for pictures or animations. When just displaying text, the spacing isn't as noticeable.Since this is going to be used as a static sign, I only played around a little with the voice AI. It worked as expected and didn't have any trouble catching the "Hi, Glow" command. I could see the benefit if installed in a car or somewhere where the content would want to be changed frequently.

The ATOTOZONE CI-VIALD 19 Scrolling LED Advertising Sign is a neat item/novelty to own. It's great for someone with a small business to advertise in the back of their vehicle window. It's compact, arrives folded & can contour to the shape of your rear window.My biggest complaint is it's somewhat difficult to set-up & to synch because (at least for me) the instructions were a bit complicated & not easy to follow.What I also didn't like is the personal information you're asked to provide when you get the APK app prior to install, which if you set-up, you need to give some personal information which leaves you prone to malware.There are other pluses to this LED sign, like the vibrant colors & the cool flashing messages you can install but you can't put anything lengthy into it because it will cut it off & not show you your message all at once. I also like the fact that this flashing LED sign is voice activated.I can only give it 4-stars but I'm sure some techy out there can make this work for them with ease. I have very limited technical expertise so take what I say & comment on with a grain of salt.

the display is brighter than i thought it would be. the app makes it really easy to set up. i also like that it's usb so i can use it pretty much anywhere. it comes with adhesive, but you dont need it to stick it to the window. it works even through my tinted windows.

TL;DR works great, and the software makes it easy to display things though i do wish there was mroe documentation.The item comes with all the thigns you see in the images. but, there are no instructions. you must use the wr code to go tot eh webstie.the adnroid software i donlloaded requtied yu to llog into there site to then be ablle toa dd your device.thre is an ai speaker,b ut there was no dcumentation on how to use it that i coulld find.you can select one of the pre defind images or animations or make your own.its not eprfect but tis rpetty good, i stilg ive it 5 stars.the display is semi sticy and jsut sticks to yoru window of your dar or hosue with jsut a sliht bbit pof pressure and easlly peals off.lots of fun.

I've already gotten a ton of reactions and question about this LED sign always asking where I got it.The app is easy to use and you basically have no limits to what you can do on it, there's even little pre made pictures you can put that other people have made!I've only used the voice control twice and each time it worker decently and displayed whatever i wanted it toThe installation process was also super easy, it literally sticks right to your screen and you can put it any way you want it, plus they give you enough wire to hide it under your carpet of your car so you won't even notice it's thereAnother thing I can say is how surprisingly sticky it was and actually stuck to the windows and hasn't came off through the heat or cold from the last 3 weeksOver all cool product and I'd definitely recommend it!!!
