Since I have used thia product I have an average experience while using it and is quit expensive too.
The ant vr has clear glass and the picture is good in quality but one has to work hard to use the smartphone while wearing it and also lack complete black surrounding. It has no external device to operate the smartphone has is quit difficult to adjust it.
I would suggest to buy a Samsung gear. Buy it only when you are in need of vr and cannot afford a Samsung gear.
I would recommend Samsung gear personally.
