Great Build Quality With a Fatal Design Flaw
Reviewed in the United States on November 6, 2018
Let me start by saying the build quality for the actual tray is rock solid. Strong metal, powder coated and nicely shaped for *most* laptops. Unfortunately, the same build quality does not extend to the extending arms, which are the single most important part of the tray's design.
The stabilizing arms are made out of a very flimsy metal material and are "locked" in place by a single plastic knob each and the arms have no mechanism to prevent them from sliding all the way out of the clamp, sliding all the way left and right or rotating so the lip at the end points downward, meaning if one of the knobs fails, the arm is allowed to free spin and fall straight out, your laptop following it. I wouldn't trust two plastic knobs and the two flimsy arms to hold a laptop of any size or weight. Under no circumstances should the arms on ANY laptop tray be allowed to free spin left and right or rotate around their long axis as there are no circumstances where that would be of use and each situation would cause a catastrophe.
A smarter design would have two of these tightening knobs on each side, allowing the arms to slide only in and out with no side to side movement and more importantly, two failure points rather than one. The arms should also have a stopper at the end nearest the Vesa plate itself so that they would not be allowed to slide all the way out of the clamp, even if loosened and extended fully. That way, in the event of a total failure of the clamps, your laptop would slide only as far down as the extent of the arms, rather than all the way out. There should also be some sort of lip or retaining system along the sides of the tray.
I'm sure there are some people more than willing to trust this design and I have no doubt many people have done so safely, but I don't have the risk tolerance to trust a $1,000 laptop to such a poor design. After just a few days of use I couldn't possibly justify continuing it.
