Samsung's attempt at virtual reality manifested in the original Gear VR, which was essentially a suped-up version of Google Cardboard. If you have a compatible device, and want to give the Gear VR a chance, the original model is now half-off on Amazon.
To clarify, this is the microUSB model that is compatible with the Galaxy S7, S7 edge, Note 5, S6 edge+, S6 edge, and S6. This is not the 2016 model designed for the explosive Galaxy Note7 (but thanks to a modular connector, also works with older devices).
The original Gear VR has a 96-degree field of view, as opposed to the newer model's 101 degrees. The newer model also has a slightly different design and altered padding. But if you want to try out the Gear VR, there's not much difference between this and the updated model.
