Here you go:
Their ratchet system would seem to obviate the need for CAM locks (which is the only way to not have a floppy chain on regular transverse chains IMO). Although I haven't had to order chains for years, I have purchased at least two sets of V-Bar with CAM locks from Tirechain.com and they were simply superb to deal with.
But this is what they warn about diamond chains:

I have a diesel. It is a heavy vehicle. I have no doubt that I would wear through the center chain quickly in California where they require you to put chains on with a hint of snow. (That is unless you have 4x4 and M/S rated tires, which I do, so I no longer use chains. BTW as also stated in the thread cited above, with 4x4 I much prefer studded snow tires over chains. That said, there is nothing as close to a tractor than a diesel SMB in 4x4 low with chains. YRMV.)
