First, I can say: accuracy and holding power are like the original,
the drive fits easily in my Arca compatible quick release clamps
of Novovflex (Q = Mount / Q = Base).
At the bottom of the quick-release plate can also 2 (supplied) screws as
Anti-slip attached (similar to Benro PU60 etc.).
So first impression: very good,
This review, however, when long-term experience is available, again
revised to see how the exposed spring with salty air
behaves at sea.
