I liked the price of this device and since I didn't have any reviews I decided to take a chance. To my surprise very well made. It fits my A7iii perfectly. The battery compartment opening is correctly aligned. I mainly use this setup for filming. If you're planning on switching between video and photo, I'd suggest getting a device with a quick-change grip. This one is bolted on, may I add, very secure. I've banged this rig against the ground and even other metal objects while filming and it did a great job of protecting the camera.
