I disagree, I think a few of you are missing the point of these. They're never going to stop a determined thief, but if you were breaking into a house and wanted to grab some keys and make a quick getaway these add a good 15 seconds to that process, and that might be enough hassle to make people consider another car without one on. They are purely a deterrent, just like an alarm or tracker, thus they should be treated as such, especially as so many cars (including very quick ones!) don't have one. Thieves pick the easy targets normally (the exception is if you have something uber expensive/quick etc, but then most Type-R's dont fall into that category). IMO.
