Looking for an upgraded option? Explore the TM103 handheld buzzer button

The Retekess TM102 quiz game buzzer system is easy to use and designed for classroom activities, quiz competitions, Jeopardy-style review games, family games, gatherings with friends, game shows, and company events. With colorful light indicators, 3 game modes, and support for up to 32 buttons, it helps make group answering more organized, interactive, and fun.
General Mode: When the game starts, the fastest-pressed button lights up green. The remaining buttons stay unlit. The system can also be set so that up to five buttons light up in different colors, allowing the host to identify the answering order.
Rule Mode: The question can only be answered when the button shows a steady blue light. Pressing the button while it is still flashing counts as a foul, and that button will be locked with a red light.
Random Mode: After the host presses “Random,” all buttons start flashing. When the flashing stops, one button turns green to indicate the player selected to answer the question, while the other buttons remain locked.
The number of winning players can be set from 1 to 5 in “Sort,” giving the host more flexibility for different game formats.



The console has a lock function. After the first button is locked, the remaining buttons are reset and the next round can begin. If the first player's answer is wrong and you want the remaining players to continue answering, there is no need to lock it, and the next eligible player can continue.
The light colors help show the answering order clearly: first button solid green, second button flashing green, third button solid blue, fourth button flashing blue, and fifth button flashing yellow.
The colors can also indicate battery level. Green means high battery, blue means medium battery, and red means low battery.
The signal transmission range can reach 80 m (262 ft) in open areas. No wiring is required, giving users more freedom of operation and making it suitable for family games and school competitions.
The host is powered by 3 AAA batteries (not included), making it convenient for mobile use. The buttons are rechargeable, can operate for up to 25 hours, and feature Type-C charging ports.
The hamburger-sized button is larger and more comfortable to press. It has withstood 20,000 press tests for reliable durability. Both the host and the buttons have physical switches, and one-click shutdown helps save power.
The TM102 supports up to 32 buttons, allowing more people to participate in the game.
Great for group settings, with anti-slip buttons on the bottom, reliable build quality, and easy programming.
