I've bought six monitor stands in the past two months (don't ask) and in no case did this tool surface any of the stands I actually bought, all of them very popular models (i.e., high sales rankings, lots of reviews).

On another note, the competition in monitor stands has been great for consumers. A decade ago Ergotron was basically the only option for high-quality stands. Now, I just bought stands that cost 1/3 or less of what an Ergotron goes for and the quality is at least as good as the two Ergotrons I have. The quality is astounding for the price.
