When you pick this headset up, you have to understand what you're getting. This is very much a budget, low-end, try-for-the-frist-time VR headset that is powered by your phone. Its neat to play with more than anything.
Personally, I wanted to see where the technology has evolved to. I was, and currently am not interested in shelling out hundreds of dollars in order to get VR going. Not to mention that other solutions require a high end PC to run the applications for VR. Maybe in a few years I'll be willing to spend that on VR, but it is still very early in.
This particular headset will allow you to test a few apps. I have an iPhone 6S and it works well enough. The "screen size" is a bit small and clarity is reasonable. The "action button" does not work for anything I have tested it on. Also, I have to remove my phone from its case for the headset to close and latch. The front plate is actually held closed with a magnet, so if you're not careful, you might send your phone flying.
Anyway about it, you can download a bunch of apps that will allow you to test-drive VR. Google has several, one of which is similar to street view which will allow you to visit famous locations all over the world!
Would I recomend this to a friend? Sure, like I said, its a cheap and easy way to get into and test VR.
