Are wheel clamps any good at stopping scum pinching your pride and joy ?

I was thinking of buying one just to put on at night time in the garage, is it worth it ?

If so what are the good makes to buy ?
cheers tufty

 

dont know about the makes mate, but anything is better than nothing.
I know people that have put those cpllapsable steel bollards into the ground before, they are pretty good and sturdy
