Well, so far I was not disappointed, the quality of the material has überrrascht me for this price range, high-quality hard plastic, self-locking nuts, solid fittings in general. The phone itself has a tight fit without additional rubber bands and slip a millimeter. Mind in a motorcycle and a sporty driving style!
I have not gotten the One X down cross, but also the holders of this should be enough, a note of this in the attached list would be beneficial.
The only thing I could complain about would be the one in my bracket, the two plates has welded together upside down "rubber band holder", whereby the seat is vertically offset relative to the other components anything.
Appears to be only a cosmetic blemish.
