Very agile clamp from Millenium. Cheaper than the established brands, but as good.
I'm a brand man, but not blindly.
If something is good and cheaper: I'll take it, and this particular type of clamp isn't to be found cheaper without compromising on quality of the springs behind the nuts or it will have no hinge to unlock it fast.
This clamp is as good as it gets. Unbreakable too.
