Pros: This item is great. It's simple and worth getting. You may not realize it but there is a space for these in every electronic device that you own. I bought three of them and connected them all to my product. I have an iMAC that it fits perfectly into the back of, as well as a Time Capsule, and a BOOK external HD.

Cons: It was difficult to figure out how to turn it at first, I was pretty frustrated and thought I had bought the wrong ones. Once you figure out that it turns just one direction and you make sure you don't use the wrong key..ahem.., you'll be good.

Other Thoughts: Keep the Keys hidden. These are just a bit of added security for your products. Anyone can break into your home and plan on doing a smash and grab, or even at your store. But not many will be breaking in with wire cutters for a quick job, so its great to use these for your external hard drives.

Bottomline: Great price, everyone should be getting these. It's really heartbreaking to lose your things, even worse if someone else has stolen them.

Pros: - Two keys
- Long enough cable
- Easy to use
- Unbeatable price; cheap safetey for your laptop.

Cons: - Smells kinda bad, but it goes away after a day or two. Doesnt smell as bad as some ppl claim, its absoloutley usable.
- The lock was abit weird getting used to, but once you understand that you have to press in the key while turning its easy to use.
- The wire could easily be snapped by a garden-tool or whatever.
- Sits kinda slacky in the lock-slot, so it could be smart to do the "tape-mod" on it; add some black tape on the inner pins (the ones which doesnt turn around) to remove the slack.

Other Thoughts: Very cheap safetey for your laptop, and you can comfortabley look away and leave it behind for a couple of minutes. Doesnt prevent anyone from destroying it, but how would it do that anyway. Very cheap compared to brand-locks, and worked perfectly in my Dell Studio 1555 with kensington-lock.

Bottomline: Great price, cheap protection from theft. Go for it, you wont find a lock with so much value for your money.

Pros: This item is very inexpensive. If anything it's just great to have a bit of extra protection for things in your home. I live in a place that's ground level and recently my car was broken into. I figured it was only a matter of time before someone may try to steal my imac, time capsule and external hardrives if they smashed the window. So these were worth getting.

Cons: These can be cut easily with large wirecutters, but its great for a small shop or for your home for added prevention for smash and grab thefts. (but not organized crime).

Other Thoughts: The key is tricky to figure out how to turn at first, but it does fit well to an imac and external hard drives pretty well.

Bottomline: It's way way cheaper than the stores, so for the price you can't go wrong.

Pros: keeps your laptop safe from burglars, but not from people to destroy your machine... but it is not the point...
quite long cable to lock it in a table or something like that....
2 keys, l one to have at home if you lose the other one.
It fits perfectly in the security port of my laptop.

Cons: The build quality is very poor and it has a very intense plastic smell...
the end of the cable has a loop that I think I can break easyly... I hope burglars not to see it...
The keys are very poor built and it seems to break at every moment, especially when you open and close the lock.

Other Thoughts:

Bottomline: It's usefull to have one but I expected something better.
