According to their site some are, some aren't

Just beware of old used items. Buy new, problem solved.
Thanks guys. My plan is to transfer the Arca Swiss screw clamps I already own. I like the idea of lever clamps, but back when I bought the system I have they were not considered reliable. Maybe one day I'll anti up to the lever, but after I figure out the head and legs (if necessary).
Many have said the same, then they tried the RRS clamp. Just imagine the perfect clamp and how solid it would be..... well, that's the RRS clamp. Peace of mind when you lock it down.
