the q666 is junk. I got one to throw in the trunk of my minivan, and it's saved me some photos, but it's junk. Knobs not captive, and HAVE fell apart on me. The last leg cannot be extended, it simply isnt stable.
if you use it without extending then last leg, then it's ok. Super light is it's most positive aspect. The head is arca compatible, but junk. Any version of the mefoto is MUCH better.
