I purchased mi vr fom xiomi store and was highly disappointed after using it. Mi vr headset has a issue with its touch button on it. It heat up the phone very quickly and drain up the battery. Mi vr headset come without the head straps and havd to buy them seperatly from the market. It is mostly compatible with only mi phones. The lens of vr headset is of average quality. You could easily find many other good vr headsets in this price range. It causes stress in eyes after using it even for 5 minutes. You must go for other brand rather than purchasing this.
