网友hdydhhd评价说: Good for class game。Easy to use. Would be better if the time can be adjust for free.如果只是抢答可以用,但是限时的部分不能调,是个缺憾。
Head to head game buzzer complete with answer timer and score keeping capabilities. Great for hosting your own gameshow, pub trivia or any vs game that requires a race to buzz in first!
