The cage will not allow the battery door to open. And yes it is mounted even with the little secondary screw. Was excited, now buzz is killed.
B and H, as always, are standup kinda folk and refunded with paid return shipping.

At first this cage was a little tight for the XH2 but its built with such tight tolerance that it ends up feeling like it was part of the camera, working perfectly, mounts everywhere you might need, and the grip is surprisingly a very good fit in the hand. The best cage I ever owned!

This cage has two mounting points and a great tool

I have the tilta cage for my a7s iii and this is better in having a multiple mounting point and overall lighter.

I feel no bend or flex on the cage w my gear on it

I really like the feel and build of this cage. The extra grip length helps with handling and the cage gives it a nice sturdy feel.
