I tried to rotate the hook and it broke off.  I won't try that again and they should be fine.  I orderd the set of 50 so me breaking 1 isn't that big of a deal.  The set I bought from Bed Bath and Beyond do swivel without breaking.  They were more expensive.  So as we've all heard before, "you get what you pay for".  All in all, it is a hanger and the clothes don't fall off.
