This recharger kit for the SafetyMate Home Version is valuable for several reasons:
1) Always keep your SafetyMate charged and ready to go. You don't want to consult it in an emergency only to find the batteries are dead!
2) The charger compels you to keep the SafetyMate in a fixed location. This is important because when you need it in an emergency, you do not want the stress of the occasion to cause you to forget where you put it!
3) Comes with Vehicle charging cable so you have it on the go.
