"Great Lock!"
Highly recommend this lock! It's 6 feet long, so you can stretch it pretty far. You can wrap it around anything you want as well. There's an optional locking device you can buy that will stick to the back of a desk, for example.

The only reason this didn't get 5 stars: It seems like a flimsy system. I'm not willing to stress it to end up ruining my computer, but I worry that if someone really wanted, they'd be able to just break my computer and run off with the laptop.

That being said, the lock does give you a sense of security. I'm in an office where there's a ton of foot traffic, and yet many people do not lock their computers. I can feel confident that if someone wanted to steal a computer, it wouldn't be mine, or if it was mine, they would have to make a scene to break the lock.

Anyway, you'll feel a lot more secure with this lock.

"Easy to use and feels sturdy"
The lock works exactly as described, hence the 5 stars. Not a lot of competition for high quality notebook locks, so I feel like I was paying more than I wanted to due to lack of options. I selected the DS version because I wanted the flat keys, however, the keys are still a little large to keep on your regular keychain. The lock appears to accommodate various mounting slot depths, but this seems to add a little slack (filled in by an integrated soft rubber mount). I wonder if this slack might allow for additional stress on the security slot for thinner skinned notebooks. I use mine to secure 20" LCD panels to their desks. In spite of the minor issues mentioned, I'd purchase again.

"Security"
Makes me feel very secure in my dorm room. Would hate having to buy two laptos and only own one. Very secure and sturdy contraption.

"Secure but Tricky"
It took a lot to get this to work. I read the instructions for how to get it to lock, and it still wasn't working. I had someone else try, and it still wasn't working. In the end, I brought it to the store and they made it look easy. Its easier to get it to work laying flat then holding the security port up. I should have figured...

The actual mechanism seems to work by putting the T shaped bar into the standard security port on the laptop, and then the key rotates the little pins so the bar cannot turn. The other end gets looped around something else. It's easier to lock without the rubber around the end, but then it will chafe the metal around the port. My laptop (Gateway P-6860FX) has some wear around the port from all my amateur attempts to get it working.

Now that I have it working, it locks securely, provided I can find something equally secure to lock it to.

"Doesn't Work, No Help From Company, Will Never Buy From Them Again"
The description says that this product has a "patented T-bar locking mechanism that attaches to the standard Kensington security slot found in 99% of notebook and computer devices", yet it did not fit my Dell Latitude. Checking the online manual I finally found the list of products it is supposed to fit (VERY difficult to find on the Kensington web site, which kept forwarding me to the company's UK site). My Dell model was listed there. The Customer Service rep I spoke with told me that it would fit my model BUT I had to buy an adapter piece. The product description clearly states that it fits my laptop - no mention of an adaptor. After going round and round with the rep, who was clearly reading from a canned script and did not seem to comprehend the difference between the written description and what he was telling me, I gave up and said I would buy the adapter but that I needed it right away. No dice. He said they could not expedite it (even at my expense) and it would take 7-10 business days. I was leaving for Europe in two days. The product is unusable and the customer "service" was useless. I was able to pick up a similar product at the airport before departing; it worked fine and cost half as much. I will NEVER buy a Kensington product again.
