^^^ I would agree 100% there BroncoHauler!
It seems once a crook is inside they're assuming turning the ignition lock will make for smooth sailing---as you've witnessed first hand the Ravelco takes that away from them.
As we all know IF they want any one vehicle they'll find a way to have it. Leaving a van unattended at a campsite etc would scare the bejebus out of me---knowing someone fairly well motivated would have more than enough time to disable a screaming alarm and go about finding what other anti-theft device was engaged.
In my case if the Ravelco slows them enough to discourge their theft it will have done its job.
On another note since this thread has so far no usable answers.........the highest level of securing in any sort of device has three elements:
1. Something you have, ie alarm system/Ravelco.
2. Something you do, ie engage the alarm or remove Ravelco cap/
3. Something you know, password OR how to defeat your own alarm(s)
When those three things are combined its easier to see how they each contribute to better security. We've all experienced how locking our vehicle doors is NOT as secure as it once was---not with tempered glass so extensively used these days. That would be #2 above and its just not enough these days.
So using that information we might all be better able to construct our own better theft deterrent devices or systems. Just remember to NOT forget any of those three steps and how to defeat them when YOU want to do so!
