I ' m about to buy one . Does anyone know what gift they are sending out with some orders ? <| sep |> This reads like a commercial for Ducky . You sound like one of those unreliable narrators . <| sep |> If they are happy with it cool but do my eyes a favor and spend a tad bit of money on it .

The question is , though , whether this feature is enough to balance out whatever difference in energy efficiency between the two systems .
