Cheap but Perfectly functional.
This is over $100 less then similar solutions and works just the same. It has a great reverse polarity protector which for me is a must and does exactly what you need it to do. Skip the name brands here and go with this one. It will function just the same.

Works great with my a7sii
I pair this with a JuiceBox 95watt v-mount battery and it works perfectly. I did a bunch of research on d-tap solutions and the GyroVu was the only one that I had not seen any issues with frying the camera.

Works perfectly
Work perfectly. I use it to get more battery life out of my A7S MKII for shooting time lapses in cold climates, and it has worked without flaw.

Great for Sony A7 and A6000 series bodies
Does the job. Have it powered directly to an Anton Baur battery. It last FOREVER. When they make one for the A9/RIII it would be a great pick up

Never worked.

Lesson Learned - Toasted Camera
I just fried my camera (A7S ii) wish I would have gone with this reverse polarity dummy instead of a cheapy dummy battery. $580+ repair lesson learned. $40 is an insurance worth protecting your camera.
