Bullock antitheft device made from steel. Comes with 2 security keys.

Locks the pedals, fitted in seconds, carbonitride steel resistant to cutting, drilling, and torsion forces.

Thatcham approved.

In the Auto Express tests it took 17mins and 5 secs before the thief could overcome the security. which gave it the top points in the test.
Most thieves will have given up within 2 minutes and the added advantage is that because the system works on the brake and clutch pedal it's very difficult for a thief to get any purchase on it, he would need to be kneeling down beside the car to get to work on it, which eliminates all but the most ambitious criminals. Even he would need the right tools and enough time to work on it.
This is from the article:
"Extremely well made, the Bullock withstood massive and sustained attacks without budging.
It's strength, plus ease of fitting and competitive price, make it a worthy winner."
