Which Kensington lock is better?

[hajime]

Hello. I am considering the following two Kensington products for my new MacBook Pro 17" 2010 model. Any recommendations?

The combination portable one seems interesting but I worry that: a) the combination lock may fail and I may not be able to remove the lock. b) the coil may stratch the MBP by accident during removal. c) it seems that one needs to push the button to remove/insert the lock. If the button fails, I may not be able to remove the lock from the computer. Thanks.

I have the combosaver, and I like that the cable coils and there aren't any keys to have to deal with. It's basically just a cheap combination lock that will deter spontaneous would-be thieves. I haven't had any problems with it, but there are a few who have, in particular with the changing of the combination. Reviews.

Both locks are worthless can be picked in under a minute. Search youtube.

Somebody said that key-operated locks are easy to be picked. Others said that they are more secured than the combination locks. Don't know which side to listen.

Are Kensington locks the best in the market? Which one would you recommend? Thanks.

P.S. I once bought a lock from the university. It was from an unknown manufacturer and made in China. It scratched the area around the security slot my previous laptop!
