Theres no way a Disklok would be removed in two mins (show me the proof). I was told by two reliable sources (one a security shop and the other my old mate who used to steal cars) that they are by far the best.
I use a Disklok, Mul-t-lok (gear lock) and standard Citroen Ultrasonic Alarm/Immobiliser. I have two sets of locking wheel nuts. I park behind my mams car on the drive. The only way theyd steal mine off the drive is with both sets of keys.
If you get a Disklok, use it. My old mate told me he would break in and steal Diskloks that werent in use. With all the time in the world, a shed and some tools, you can drill out the lock and replace it using a padlock across the locking holes along the top.
Incidentally, dont assume Im like my mate, were like chalk and cheese. He went one way at 13, I went another. Rarely see each other now.
