As we attended more events to conduct lucky draws, we had to be there before the event started to brief the MC and sometimes the client on how to use the digital lucky draw, and to rehearse. That led us to introduce the Big Red Button for ease of use.
In the earlier days, it was just the space bar of a notebook that ran the lucky draw software. This progressed to a homemade button using a USB foot pedal that also did the job — but we were not satisfied.
It really got stylish when we were able to source a Big Red Button — what some clients call "the buzzer" — that worked wirelessly even in the biggest halls and ballrooms. We tested it in many large halls, and it worked smoothly without interference from the other wireless equipment in the venue.
Event organisers and customers insisted on the buzzer, and some got hooked on it. It was a nice introduction, and customers loved it.
Today, the Active 2.4GHz Wireless Big Red Button is available as a product for lucky draw operation.
