I'm sure most of you have seen this video on Masterlocks anti bump pin. http://www.youtube.com/watch?v=kUJWc7rIj8I

I would like to hear your thoughts on this system actual effectiveness.

Opens with a modified bump key and that is where the "4x more resistant to bumping" comes from: in 4 pin cylinder, the "bump stop pin" can be in any 4 pin locations and thus you would need 4 different bumpkeys.

In my opinion: Crap.

I also think having this kind of pin will make the lock easer to SPP.
