The Quad Lock mount is well made however it was a bit of a faff to fit; Aligning bolts under the screen was frustrating with the cable retaining clip bolt (small and on the front) being particularly annoying as it was drilled ever so slightly lower than the screen which made getting an allen key to it very difficult. But once it was all fitted up it positions my phone perfectly above the TFT which is a great addition.
Great service from the team who very kindly helped me on the phone and shipped the same day even though I was after the cut off for dispatch.
