This cable, lock, and eyehole attachment set is a decent theft deterrent for any device that has a built-in security slot. A determined thief won't be stopped by this system, of course--any lock system that depends on a security slot has an easily exploitable weak point, especially on anything with a plastic case--but it should be sufficient for uses where the protected object is not left unattended for long periods.
*The security cable is about the thickness of an Ethernet cable, while the padlock (including the shackle) is roughly the size of a Zippo lighter.
*The eyehole attachment is not particularly robust and probably shouldn't be relied upon for securing irreplaceable equipment or in high-risk environments.
*Both the padlock and eyehole attachment are sheathed in soft plastic so that they won't scratch or ding the device they are securing.
*A travel pouch and a brief instruction sheet are included.
Bottom line: an acceptable setup for home, mobile, and attended office use. A stronger eyehole attachment would be a major improvement. 3.5 stars.
