Virtual Reality Headset Goggle Tech Go4D VR Image & Video Viewer with 3D Virtual Reality Capability (White) for Android & iOS Smartphones (Apple iPhone 5/5s, 6, 6 Plus, Galaxy S4, S5, LG G3)

I ordered this having used:1. Google cardboard.2. Zeiss VR One3. Samsung Gear VR4. Occulus RiftIt is barely adjustable and did not fit my LG G3. Even with what could be adjusted, I could still see the edges of my phone and read the LG Logo. VR doesn't work like this... I was super excited and wanted to try this version. Unfortunately, even the VR apps that were designed specifically for this aren't as good as the current competition. (I was very upset at the quality because the price point is the same as the Zeiss VR One and the Zeiss is substantially better...)If I find that I am an idiot and their is a way to adjust it in a meaningful way, I will update my review. However, I am usually pretty good at stuff like this and I wasn't even willing to let my wife try VR with it. She has never seen how awesome it can be, this would have left her thinking I was insane.

Where do you get the iPhone 6 plus cartridge at
