What It Does: This two-way radio-frequency system, which is available in two formats, Q4 RF and Q5 RF, is designed to work well in groups of all sizes.
Why It's Different: Keypad uses an LCD screen, and users can request help by using the keypad. Presenters in multiple rooms can use systems next to each other without conflict. Personalization also is available, and the system is designed for game play.
Cost: Qwizdom is priced per device, and the hardware comes with the software. Qwizdom CEO Darin Beamish estimates that the cost of 30 devices would be about $4,000.
