This is also the first I've heard of Kickstarter.

saw this in a tweet from wired

Looks alarmingly flimsy, but it is titanium. Wonder how strong it is...

about 120 kpsi yield strength for "plain jane" 6-4, which is on par with hardened steels.  That lock will keep the general riff raff away, but any smarter riff raff with a cordless grinder and carbide wheel will be through that lock (or any others for the matter) in about 15 seconds.

a determined thief will always get what he wants. But any device that makes it harder to steal pays for itself easily.
