Getting a good fit is the first step on a journey in VR.
Gear VR is one of the more accessible VR headsets available right, as well as being a pretty comfortable fit. Before you go diving directly into VR though, you're going to want to adjust the headset so that it sits correctly on your head. After all, who wants to start enjoying VR only to move their head and have their headset slip off their face?
This is how you ensure that never happens.
