These buttons were used for an interactive game in a public place. They worked flawlessly for three days. I used 32 buttons, each pressed hundreds of times. The only point of criticism is the tiny connection lugs. I had read other reviews that said the buttons could melt when soldering the connections, so I opted for tiny solderless spade connectors which were cumbersome to use. It's not really a button bug, but still an issue when using it.
