Really work!
Bought these for my friend and me to use. We live in two different states. I was a little nervous on if they would really work but they do! Setup took a few minutes and within fifteen minutes we had gotten the hang of sending each other messages. You need to press the two buttons for a bit to change the colors but I didn’t press them hard just kept my fingers on them until the color cycled. I would recommend them to someone considering. They are easy to set up and flawlessly send messages.
