The old Toshiba has like a huge 1 inch gap so I am not surprised that it didn't work here. Nowadays most people have a 1/4" gap between screen and keyboard so the lock would work. I have a Acer Spin 1 with no kensington slot at all and also a Lenovo Ideapad 330s with a Kensington mini security slot that only works with the Kensington 67890 Minisaver Mobile Lock which costs $45. With this Griffin cable lock, I can lock either my Acer that doesn't have any Kensington slot or my Lenovo. It is much cheaper and the theft deterrent is pretty much identical to any Kensington lock. Both Griffin and Kensington locks can be cut with like a 14 inch bolt cutter but like 99% of laptop thefts are grab and go. Most laptop thieves aren't using tools. The robber wants to the quickest and easiest target. They can play tug of war on this lock or a kensington lock but it will damage the laptop kensington slot or THE SCREEN and it will bring lots of attention to them. Last thing they want to do is destroy the screen.... This is a deterrent for leaving your laptop unattended for short periods of time like in the library to go to bathroom. I wouldn't leave an expensive laptop locked up for a long period of time in a busy starbucks in NYC where a bike thief may have a bolt cutter in his backpack..... Don't forget to loop the cable around a table leg that is bolted down and that can't be lifted up easily. You could also loop the cable around some part of the table where it can't be detached.....Update: I cancelled my order for the Kensington 67890 Minisaver ($43) because I feel the price is expensive and the Griffin lock works just as well if not even better because thieves are less willing to do the YANK method that cracks and breaks the Kensington slot but makes the laptop still working perfectly fine. A thief would most likely damage the screen in a yank method with the Griffin lock. Can the plate be bent and slip through with a tool? Yes but this isn't aluminum and is tougher to bend. I think it will take longer than one expects with pliers as the plate isn't tightly down like in a vice. It moves and the leverage isn't there. If I were a thief, I wouldn't be wasting my time in using to pliers or trying to pick the combination. I would just go for cutting the cable with bolt cutter and that is really the big weakness for all laptop locks and not just Griffin.
