Review on 🌡️ Coolbird Temperature Rechargeable Restaurant Exhibition by Jaleel Pruitt

I already had led icons but bluetooth is a game changer. You can program up to 8 messages on your mobile phone and easily send them via Bluetooth. Here are some things that I don't think are clear or should just be mentioned again: 1. Use an app called LEDBadge. It's simple but worked great on my iPhone. Just point your iPhone camera at the QR code and you will be taken to the app.2. Top Right Button - On/Off/Bluetooth. You don't need to pair the device. Use this button to show the Bluetooth icon when you're ready to receive messages from the app, then tap Send in the app. No need to pair like Bluetooth headphones and speakers.3. The bottom button is used to toggle between messages (up to 8). Hold to switch between brightness levels. I found the app ok. I wish there was more documentation on display options, but message loading is fast if you're willing to experiment. Wishlist: I need one of the portable LED fans with the Bluetooth programmability that this icon offers. multiple devices with a lower unit price. Update: This hasn't worked for me for a while. The error message was in Chinese, which was frustrating. I took a screenshot and translated it using a popular translation program written by a popular search company. There is an input line for up to 8 messages. In addition to filling the line with the message, you must move the selector to load each line. I had configured the slide to load an empty string.
