Green LED Sign

App difficult to download but worked it out eventually and works well Egnore QR code with product instead download 'coolled' from play store and this connects to the board. The board itself is small and cute, great desktop size or for car window if you would like. All in all happy with product.

Top product, easy to use and connects quickly

Works really well ONCE you actually find the correct app to control it. 3 different QR codes to download different apps and none of them would control it, a short YouTube video later and I finally find the correct app! However product is great and very easy to install and set up!

Unbowed today, does not work with the recommended app, had to locate an alternative as would not connect via Bluetooth. Once I located an app recommended within amazon questions I was able to connect. I uploaded my message and then the screen cuts out as in the video. Not able to upload or change the message. What a waste of time and money.

Not a bad product, you can program messages, graphics or link to music. However there doesn't appear to be any way to STOP the message once you've started playing it. Also couldn't get the software to install on Android head unit, only on my mobile. Bluetooth just didn't see the device. However that MAY have been the head units fault.

Bluetooth connects great, can change message without having to point directly at the bar. Fairly flexible with speed adjustment, scroll left up down etc etc. The only bad point is that the suckers are next to useless. Both sides have failed to stay attached within the first hour of use. Prob get away with a piece of DBL sided tape to secure them but as I intend to move it from front screen to back screen and back again on occasions it's a shame you can't rely on the suckers.

The sign itself works fine but the issue is it is white (fault on my part) and the cable barely stretches to the front where the cigarette lighter is which is a bastard also the rubber suckers are sht at sticking but other than those faults it is fine Also forgot to add the size is mismatched in the description as to the actual sign the seller did not state it was a mini sign in their advert (fault on their part)

I asked if this would work with windows PC's in the questions, one person said 'yes, it works on his pc's' So i bought it, found the apps from the qr code (there was 2 that i tried), none will connect to the sign, my pc used a bluetooth dongle, my laptop had built in bluetooth I don't own a smartphone, but it might end up as a gift for someone in the family who does.

Es de un tamaño pequeño, aun así cumple su función. Yo tengo el cristal tintado al nivel mas oscuro ( coche) y aun así de noche se ve.

A prioris pour l’avoir essayer ils fonctionne très bien plusieurs format possible , changement de luminosité et de vitesse de défilement

Il prodotto corrisponde a quanto atteso, ma le istruzioni in merito all'app da scaricare non sono chiarissime (il qr code rimanda solo al sito web, ma non ci sono riferimenti all'app da scaricare). Dopo aver contattato il venditore, ho appreso che l'applicazione da scaricare da google play fosse "CoolLed1248". Una volta installata, è stato possibile collegare la stessa al Bluetooth. Consigliato

Tolles Teil und werde es diese Woche an die Heckscheibe montieren. Einfach die App installieren und los Texten. Was ich bemerkt habe ist, dass nach einer Woche, die "gespeicherten" Texte in der App weg waren. Nicht weiter schlimm, ist ja einfach zu Programmieren. Kann ich nur empfehlen.

Barre led très bien, juste un peu petit par rapport au prix. Installation rapide et changement de texte à volonté.
