I have lenovo vine k5 plus and I always love entertainment and watching movies videos etc . So I buyed an ant vr for my lenovo device . I experienced it it was so good not like other vr headsets . Other vr headset has full closed behind the phone which makes the phones very heat . But this vr has nothing at the back of phones so no heat is produced . Overall built quality is good.strap of vr is flexible and good
