Guitar security: better than nothing "Rock Lock"

Just saw this:

It's basically a bike lock that had sex with a capo
Looks like it attaches to your amp or some other object so someone cannot walk off with your guitar. While it keeps off the casual "walk aways" it won't stop the true professionals.

So the question is... is it worth $40???
I'm debating whether to give it a go.

One of the more mysterious elements of the green guitar, which Francis Rossi apparently repainted personally with green fence paint, relates to the hole that's been drilled slap-bang through the middle of the body. Although various stories have been perpetuated and circulated over the years regarding the hole's origins, Lloyd believes he has found a fairly plausible explanation, despite the fact that Rossi himself will never quite confirm the real true story.
"A lot of it is done tongue in cheek just to keep the mystery surrounding it!" says Lloyd. "You don't want to give everything away; that's one of the main things about peoples' great guitars isn't it? Keep a little shroud of mystery about it. But as far as I'm aware through talking to a few people, the hole was put in the guitar (and some others) so that back in the day they could put a bike block through them to stop them getting stolen, because they did actually get stolen at one point.

by putting locks on your gear you are giving out a very poor vibe to the audience. Basicly saying saying you dont trust them. If fans have access to the stage, dont leave your guitars on it (surely you need them for warm up and tuning off stage anyway). Or take a mate and have him stand over them. If I saw a stage set up with a bunch of locks on stuff, I would honestly reconsider watching the show.

I don't think this is the case at Detroit area venues. People aren't going to notice that's a lock or bother to look that closely. Also, I gig out with nice guitars... 70's Gibsons and stuff I enjoy playing. Lots of places I can play punk shows at are not in "great" areas. Having a guitar "hidden" in a case allows someone to walk off with your guitar in its case. Happens all the time. So lots of times, I never stray more then 10 feet from my guitar, or at least keep a constant eye or glance on it. On larger stages, opening bands setup in front of the other two band setups. Everything has to be out so there isn't a ton of time lapse between sets. In some cases, it's just as much so other bands don't walk off with your guitar as they are breaking down their gear. Like a singer "trying to help" didn't know what guitar his guitar player had. Sometimes an honest mistake, sometimes not. Most fans that come to see us are friends so they wouldn't get offended if they saw a lock on my guitar. Most other people wouldn't even realize it's there. The thing is 40" long so if anyone was that worried about its appearance to spectators, the guitar could be placed behind the Marshal stack, so audience couldn't see the security. But not me. Even locked, I'd still want to keep an eye on it.

Most national touring acts have some form of security. Joe has personal security for his '59 Lesters. I see value in $40 if not for true safety but for piece of mind if anything.

just my two cents
