There is a newer version of this product: MicroSaver 2.0 Keyed Ultra Laptop Lock (K64432WW)
The MicroSaver® lock head features the patented T-bar locking mechanism. The T-bar provides a tight fit with the Kensington Security Slot. A rubber bumper ensures a snug fit between the lock and the security slot and protects your hardware. A further deterrent is the tamper evident feature. When a Kensington MicroSaver® lock is tampered with, it locks itself down and can even trap foreign keys.
All laptop locks are not the same; locks differ based on lock technology used, the ease of use and the level of security provided. This MicroSaver® lock is built to exacting engineering standards.
