Unless you are a country boy like me, you may not know the utter importance of the two finger wave. If you miss one, you have just caused one of your neighbors to wonder WHAT THE HELL IS WRONG WITH HIM TODAY???
And just so you know, the really cool farmboys sometimes do the wave with only ONE finger. Imagine how cool you would need to be for that??
With this device you will not miss another one. This is excellent.
