RBS 850, RBR 850, are the panels on the body loose?

[vikrantl]

I received "new" RBS 850 & RBR 850

the panels on both are loose, shaking.

Is it the case for all 850 items?

For example RBR RBS 750 had firm (white) panels

Or is it a refubrished devices?

They should be tight and NOT loose. I'd return the entire system and get another.
