Arca-Swiss at a good price

The terminal is very well processed, adapts well to the lens clamp and fits perfectly. You have to tighten the thumbscrew wzar a little harder, but then relaxes nothing and you have peace of mind when using or "hanging out" at a Sunsniper.
Sharp edges can be a good piece and miss, only the big screw and the surface quality are not very successful, anodizing goes quickly (contact surfaces for Arcaswiss terminal), which makes but with the price and feature nothing.
For those who like me use the terminals of Sirui with en safety pin at the center (super if you the Arca-clamp times but not properly tightening), these snaps perfectly into one of the thread on the bottom. Another safety point for the flying change.
For users of the Nikon furnace tube full recommendation
