This business attache case is backed by a lifetime warranty from Zero Halliburton, which would be expected since it retails for just shy of $300 USD. Unfortunately there is no dedicated notebook pocket inside the case (other Zero Halliburton cases are more catered to notebooks, except none of them seemed suitable for the new Retina MacBook Pro I planned to house inside), but when tossing the notebook inside a notebook sleeve it seemed protective enough and didn't cause any problems.
For securing the attache case itself when in say a hotel room, there isn't any lock slot on the briefcase itself. What I ended up doing in Nicaragua for securing the laptop within my hotel room were Smith & Wesson handcuffs as the locking mechanism. That worked out fine and my laptop inside the Zero Halliburton case was very secure. The only problem with this is then having to worry about the handcuffs. Private citizens within the United States are allowed to board aircraft with handcuffs; TSA has no problems with it and they don't even question you about them when clearing security, at least in my experience. However, when clearing security in Managua (Nicaragua) to return to the United States, there the security personnel did have big problems with non-law-enforcement personnel having a pair of handcuffs. It ultimately took several minutes of questioning and confiscating the handcuffs before the Nicaraguan security let me through.
It would also be nice if Zero Halliburton manufactured some sort of outer-covering / sleeve for the S1 Premium Slimeline Attache so it could have a shoulder strap and some additional pockets plus looking a little less conspicuous when walking around with a briefcase made out of aircraft-grade aluminum.
Overall though, for anyone looking for a highly-reliable and secure notebook case, the Zero Halliburton S1-SI Premium Slimline Attache should be able to serve its purpose very well and I have no other issues with it after using it for several weeks thus far.
