Hi, Im looking for advice on which security devices (especially chains) that people would recommend. Is it worth the additional expense of an 'insurance approved' device? Does such a device offer enough insurance premium discount to be worthwhile? Im aware that nothing can stop a determined thief, just wondering if its worth me buying a new device, or just stick with an old magnum chain i already own. Scooter will most likely never be left in high risk areas. Thanks in advance!
