If this review was for just the trunk anchor, that part deserves 5 stars (genius idea, great execution).

However, the keys for the 6' OnGaurd Cable lock are way too flimsy. As you can see in the photos, I broke two of the five supplied keys just trying to unlock the cable. At first, I couldn't unlock the thing at all with any one of the keys & had to try several times (breaking two of them in the process). And this happened the first time I tried to use this lock. (See also my review for the 10' cable lock.)

I've used several OnGaurd locks & cables in the past and have never had trouble with them at all: they are usually well-built, quality-made products. I have no doubt these particular locks will work well, but am disappointed that the keys don't seem to reflect the quality with which the other parts are made.
