Nothing actually wrong with the mount, but with it being attached to the screen fitment, when the screen is at its highest setting there is a fair bit of vibration on the SatNav itself. The lower the screen reduces this vibration, but not perfect. The handle bar mount would be more sturdy but the SatNav obscures the clocks, plus you have to look down at the SatNav. So it's a trade off between eye level contact with a bit of vibration or a sturdy positioned SatNav.
