Good, but needs improvement.
It works great. The buzzers work smooth on all phones. Few things I don't like, such as how even after the person's name is highlighted on the host phone, you still need to tap on there name to add or subtract a point. Also I would like to have it so you can make it so there is no penalty for an incorrect question. I also think when someone taps the buzzer, the host phone should just have the buttons appear big so the host could just tap "correct" or "incorrect" and automatically score accordingly.
