Why isn't the buzzer available with Bluetooth?
A wireless Bluetooth solution requires batteries that need to be replaced almost every month if the device is used on a daily basis (because of the LED). That's too unreliable for us. The buzzer is intended to be used at the workplace, and should work absolutely smoothly. You can also use the timeBuzzer App with a keyboard and mouse when you're on the road, or you use the mobile apps.
