Datexx Miracle Cube Timer

Great little Miracle Cube Timer is a little too noisy. To fix that I replaced the buzzer with a cell-phone type vibrator. I unscrewed the cube, 2 screws (with a Phillips driver), clipped out the little buzzer, and soldered in a 3VDC Micro-Vibration Motor (RadioShack Model:273-107). I think it is better, what do you think?
