ADVANTAGES Attractive shape. Careful workmanship. Comfortable optics mounting provided (inspection holes for Torx key). DISADVANTAGE Unfortunately, one thing didn't work for me: the clamping system in the form of a small tightening knob instead of a hex or Torx socket. Disadvantages of using a tightening knob: 1) The tightening knob protrudes below the lower plane of the mount base, so it can rest against the element to which the mount is attached and prevent proper fitting. 2) The tightening knob is not offset from the mount body (probably for a "flat" side profile), so there is very little space to grab it with your fingers. 3) The tightening knob is difficult to unscrew with slippery fingers (they could, for example, add a diagonal slot for a coin).
