Even if execution of the componets looks very nice and the tutorial on how assembly is really well done, the TomTom device is vibrating and generated a sort of slightly flickering. I'm sure that I followed very well all the instruction during the assembly, but I don't like this issue on a GPS stand. Please try to improve and remove the small vibration that will compromise a very good design of the gps support, so my judgment is the mid low score range.
