Since these devices are magnetic, when should I be extra careful using them?

The devices will stick to metal. If you are wearing a device on a wrist or an arm and move a pan off the stove, the device may stick to the pan and could potentially cause an injury. It is important to use extreme caution if the cookware is attracted to magnets.

Also, it is imperative to keep the devices from coming in contact with someone's pacemaker or internal defibrillator. Direct or very close contact of the Q Magnet device to the pacemaker or defibrillator could cause a malfunction to occur that may be life threatening. Please consult your physician if you have questions about potential risks.

The devices will stick to a chair if the chair is made of iron. Be certain to use care and not expose the devices to computer discs or video tapes. Always use caution when using magnets while piloting a plane.
