When looking to purchase Lifesaving Equipment one should look at gathering as much information to determine if the AED (Automated External Defibrillator) purchased will help a victim of Sudden Cardiac Arrest 100% of the time as well as the cost associated with owning the device. We only distribute/sell ZOLL Medical AED products. The quality and dependability is there, as is support. We do not work with refurbished or second hand devices, only warrantied, from the manufacturer devices/equipment.
