KensingtonMicroSaver Retractable Keyed Laptop Lock (K64538US)

After using this lock for two and a half weeks, I have finally figured out how to retract it fully and easily. I'm mostly writing this review to let others know too.The problem is that the retraction depends on some oomph in the mechanism (I don't know the exact terminology). So If you try to retract it slowly while guiding it so it doesn't flip around wildly, it won't go all the way back in. If you just let it flip around wildly, someone is likely to get hurt, because the lock head is heavy duty (RIP my right middle knuckle).What you need to do is hold the lock head right by the spot it goes into, and then press the button. This allows it to retract fully without flipping wildly.A few other notes:- This little guy is strong. It looks dinky, but it holds on tight. I have been using mine on my daily commute, which usually means using it to chain my suitcase to the mostly-empty luggage compartment at the bottom of a charter bus. When I get off the bus, it's clear that the suitcase has been jerked around, but the lock is holding on strong. (I've figured out a way to keep the suitcase from moving around so much so it won't continue to strain the lock, but I am impressed that the lock has done its job.)- This guy is a time saver. When studying in public places like libraries, all I have to do is pop my laptop back into my suitcase and use this lock to chain it to something when I need to go to the restroom. I don't have to pack everything up and drag it with me, and I don't have to worry about my spot being taken when I return.- The only real tricky thing is figuring out how to lock and unlock the mechanism. Once you get the hang of it, however, it goes really smoothly. First, you put the key in and twist while also pressing down. This gets the X shape of the key to align into a I shape. Then you put it in the lock, twist, and twist again to remove the key.All in all, I'd highly recommend it, especially with the Kensington SecureTrek Laptop Roller, which is the suitcase I use it with. (I'm not as enthusiastic about the suitcase, and this is not a review for it, but it is one of the few of its kind - lockable, commutable, small but holds a lot - that I have found.)

Well I suppose the only way to find out how strong the really thin cable on this is, is to go at it with pliers. But I am not about to do that. Keep that in mind. There'll always be some uncertainty and doubt in your mind about leaving your precious laptop behind.I wish that Kensington had something to say about that - surely the thin cable is the first thing people will wonder about when they see this. Does the absence of any reassuring words mean that (1) they do actually know that it isn't the most secure and/or (2) that they think it is more a deterrent than a real security measure, but saying so will hurt their chances of selling this?The only way to cast some of those doubts away is by using it in a relatively secure place to begin with, some place that has a steady flow of people in the first place. I would not leave my laptop behind in a coffee shop or my library or student lounge, without locking it. And in those places, I wouldn't mind using this, because any miscreant trying to fiddle with the lock or the cable is bound to be noticed. But I would probably use this only in those kinds of places. For anything that you would deem less secure and/or more secluded, go with the thicker cables. (The reason why I bought it in the first place is to use in my library, the Grad Student Center and the Chinatown bus, so I'm quite pleased with my purchase.)The length of the cable could be a bother for some people too. It really is quite short. On a regular size table, you computer cannot be more than 1.5 or 2 feet from the edge/corner if you use this on the front leg of the table.Unfortunately there isn't much choice out there with retractable locks (which is something I was looking for). This is the only one by a company of some repute. I searched about aplenty, including a bunch of computer stores, but this is really the only one.The price on Amazon is quite good. I don't follow however, why it moves around about $1.Hope this helps!

Comprei fui testar no Notebook de casa. Travou e não abre mais. Entrou em lockdown mode.Agora estou com o cabo preso e não abre.Registrei e falei com o suporte nos Estados Unidos e falaram que precisa de uma chave mestra.O pior é que ficou preso no notebook da minha esposa.Que desastre
