When I bought this I had something else in my mind in terms of what this device would do, and when I used it I realized I would not be using this. For one thing, it didn’t fit nicely with my huge phone (Nexus 6) with the cover on or off. It was too much hassle to put in and out the phone. Plus I didn’t know the videos had to be in a 3D format to be able to see it. I wanted something that makes the screen bigger, but this doesn’t do it, so I decided to return it. I put it back to the box, then I forgot about it until it was too late for returning to Amazon.com. I used this only once, and that’s all. This works perfectly fine; I just don’t use this. I paid $19.49 plus tax.
