When purchasing my car security device I read many reviews of other products complaining of flimsy rods or locks. This lock is STRONG and heavy. Neither a hacksaw nor a hammer can break it. It took me a few tries to find the correct position of the lock relative to my steering wheel. I finally settled on a 90 degree turn and roughly a 4 o'clock position on the steering wheel with a knob located in front of the shifter on the console. In this position of the lock turning is almost impossible. The bright yellow color is highly visible and should deter anyone who is about to break into and steal my car. I am very happy with my purchase.
