Is cheaper than the original by the camera manufacturer but just as functional. However, I will not conceal the 2 small makos, which are partially not be changed:
1. Due to the screw can no longer hang smooth the camera. This can not be changed constructional reasons.
2. The bolt should be checked regularly for tightness. In Gegnsatz for Quick Sling Strap Slider the same company here is not rubber, etc. betw. screw and camera body, which prevents untwisting s or at least minimized. So check from time to time the seat of the screw
A suggestion I would have: I sometimes Change on the Quick-Sling, faster attachment to the strap hole would be desirable. eg a carabiner or maybe tighten velcro. So you always have to carry the strap through the eyelet and then adjust the width by fixing the terminal.
In principle, I am very satisfied and would buy the part immediately.
