I did not know exactly what to expect with this device but I have to admit on first impressions, I am pretty impressed. Even the packaging shouts quality, Xiaomi always seem to provide top quality gear and this is no exception. Easy to pair and initialize , although before using it, an update was installed before I could get a look inside..The potential with this device is huge, the Oculus rooms have a really good social potential if Facebook decides not to continue bulldozing users to connect everything to FB. I highly recommend first installing Jurassic World Blue and watching (actually experiencing it is a better word) This shows the true potential of VR when done well. Very glad that I purchased this and have to commend Prime, I chose expedited delivery and it was delivered Monday morning - I ordered it Saturday night, great work Amazon, very happy customer! -Update - the GO is a great device but the battery life is a little underwhelming, I recommend a Power Pack (you know the ones to power up your phone) , First fully charge your GO then plug in the power pack -keeps the GO at 100% and runs from the power pack, does not ever get hot and lasts for ages, longer than you eyes could in VR :) I am using a Xiaomi 20000mAh bank and it works superbly with the GO, obviously if you are standing or whatever you will want the powerpack in a pocket etc.
