I recently split intensive exercises. Since these exercises are pushing to end, it's hard to stay focused to count the exact number of seconds and between exercises. The miniMAX allows not having to reflect, to put the focus on training. We can calibrate any type roughly Alarm: simple, repetitive, multiple intervals .. with or without sound, with or without vibration .. I coupled to the shell and also sold Gymboss strap on Amazon, and I do not regret my purchase. Note: requires a AAA battery not included. Not yet able to test autonomy, but I imagine long given the nature of the equipment and the fact that it turns itself off off exercise.
