Do what it suppose to do. Cool bell-sound at the end of the round. The only flaw: it keeps the time for maximum 12 rounds (but you can work it out, because after the twelfth round there is a round brake, so after the end of the round break, just press the start button and start over, keeping time for another 12 rounds).
