Protect your laptop against theft with this low-key four-number combination lock. It is sort of like the lock you put on your bicycle. It has a self-coiling cable that stretches from 3 inches to 6 feet, I wonder if Stretch Armstrong had any thing to do with this innovative product. The ComboSaver plugs into the Kensington security slot found on 99 percent of laptops. The colors available for this lock are red and gray and the cost is 25 bucks.
