Not much you can say about this other than it does the job you buy it for. The lock is a little fiddly, but I think that's down to the way it fits into the laptop rather than anything specific to this model. I feel just that little bit safer if I'm working in public that no-one's going to be able to quickly snatch my computer without taking the table I'm sitting at too.
Open the pack and saw it looked the business. Had some difficulty in getting the 'male' part of the device into the slot in the laptop but eventually found the right method. Key and lock barrel was a bit stiff and it took a few goes to work out the right technique to lock the device in place and not un-hitch it from the laptop slot at the same time. Would work better with a 'proper' key and not a rather odd-looking cylindrical key. In otherwords a bit fiddly to install but once you have the hang of the method it's a lot easier to do it a second/third time
This is a simple, sturdy piece of kit. It won't stop someone with a pair of bolt cutters nicking your laptop, of course, but it's a good deterent for the opportunist thief. Pretty good value, too.
