This is the Staples Easy Button. They sell them for $5 each. When you press it, it says "That was easy!"
Some folks have been hacking them, trying to be able to record a new saying on them. I didn't care much about that. What I see is a big-ass red momentary switch for $5.
What can you do with a big-ass momentary switch? Replace the crappy little doorbell switch that opens the garage door, the one that rarely works, the one that's falling apart.
