Good but could be a bit better

Comfortable. Feels solid and expensive. But one thing makes me cry - if it is connected to Oculus then it constantly provides power even in Oculus is fully charged.. so green led will be constantly on on the Oculus... Needs some on/off switch or some technology that would sence that internal battery is full and then it stops charging oculus
