Frnds!.Few months I bought my lenovo k4 note mobile phone. And I also ordered lenovo antVr headset. Along with it. But when I used it. It was just 1 star type virtual reality headset. So I gave it only 1 star.quality of material is OK OK. And on the tym of using it .very sad performance. If u guys really wanna buy. virtual reality then don’t buy this product. Go for other. From my side I give it a onlyyyy 1 star.:(
