Seems very strong. All metal. Arca Swiss compatible plate is a nice bonus. Be sure to check all tiny hexagonal screws before using it! Using a tiny bit of glue does wonders making sure does screws will never get loose. Of course the holster and plate are not anodized, there are some rough edges and paint may chip, but overall it feels very secure and solid and I trust my camera to it.
Awesome stuff for a good price.
