Would someone who has owned both VU+ Duo and now own a Gigablue Quad please comment on the sensitivty of the remote and more importantly the IR sensor on the actual receiver.

Currently I'm using a duo which is tucked away and only partly visible behind a wall, but I am still able to use the remote effectively without a direct line of sight. How does this compare with the quad. I know wi the duo you could even change channel with the remote facing the opposite direction of the receiver. Is this possible with the quad?
