Almost every piece of computer equipment these days are already equipped with the Kensington signature lock, so with the Microsaver (made by Kensington) there's no worry that you'll order a lock that won't fit or is just too flimsy and untrustworthy to use. Companies such as HP, Compaq, and Dell detail their equipement with Kensington lock slots. Even these corporate giants trust this lock.

I suggest the Microsaver Slim, because these days, laptops are so small that you don't want to end up with a lock that lifts your computer off the desk or have to cram a larger lock into a small travel bag.

Kensington also makes a ComboSaver, which uses the same technology and is equally reliable, except that a 5-digit combo lock can be cracked in a matter of minutes. The Microsaver comes with two keys (both are identical with ID engraved; one for a spare), with a sleek design that looks cool on your keychain, too. :-)

You can register your lock at Kensington's website, so that if you lose a key, you can report to them and they'll send you a new one to match your lock.

Lastly, the cable is sleek and very strong, and will easily support a laptop's full weight. The locking mechanism even has a rubber stopper on the end to avoid scratching your equipment.
