    Comments about Targus® PA400U DEFCON®1 Ultra Notebook Security System:

    I have used this item for several years while traveling and using my laptops at trade shoes and leaving the machine in hotel rooms. I started using it again this year after not using it for 3 years. The battery was still good and it worked perfectly for our current trip. I was surprised that it works with my new laptop.

      Comments about Targus® PA400U DEFCON®1 Ultra Notebook Security System:

      I got this, even though I thought that [$]was way pricey, and was severely disappointed. It tells you that you can simply click the cable back into the main body of the lock and thats all there is to it. Yeah, right. You must have to be a bodybuilder or something. I couldn't get it to click in for the life of me. I would recommend not purchasing this, like seriously, and going with a more traditional, thick cable combo lock. They're cheaper anyways. Still have not gotten my refund... and its been QUITE a while now...
