Combination Lock Security Cable

I wish I bought one of these a long time ago! I work from home and like to get out into coffee shops and other places every now and then just to get out of the house. The problem is that if I'm sitting for a long time in a public place I'll eventually need to get up to go to the restroom or do other things. With this lock I can loop through a fixed table leg (or other furniture/fixture), loop through my backpack and lock off to the computer. This at least makes it difficult even for a brazen thief to attempt to quickly grab my stuff in a public place while I get up momentarily. This gives me a little more piece of mind so I can more comfortably get out of the house to work and for longer periods of time. As for the quality of the product itself, I haven't used other notebook locks so I don't have much to compare to. However, I haven't had any troubles and I couldn't expect this thing to do more or work better. I read some reviews about difficulty setting a new code, but I found this to be pretty easy (just read the instructions, but it's pretty intuitive... set old combo [0-0-0-0 is factory set], push/turn screw on end to vertical position, set new combo, return screw to original position). The red color makes it harder to accidentally leave it somewhere. I use a small velcro strap to keep it in a loop when it's packed in my bag. I've used it it with two different types of computers so far (one is an Asus and the other an HP) and it worked perfectly.
