Review on 64149 Kensington Microsaver Retractable Notebook Lock & Cable: Ideal for Mac or PC Security by Lokesh Das

Just received this lock and am very happy with it. Fits my HP with no problems. The castle got a bad rap from other reviewers in my opinion due to unrealistic expectations. I'm sure the cable can be broken easily, maybe even with a heavy pair of scissors. It's not a safe, but it's a deterrent to a would-be armed robber and should give you some insight if you leave it on the table for a few minutes when you go to the bathroom at Starbucks. That's all. It is excellent for this purpose, nothing more. If you need a bigger lock, definitely don't buy it.
