Product comparison

Superior vs competitor product comparison chart

Fig. 1 shows the Superior Arm deflecting only 4.1mm under load with real-world load points.

Fig. 2 shows the Competitor's Arm deflecting 24.91mm under the same load points and loads, almost the same as the width of the Arm itself.

Also of note is the Competitor's Arm deflected to a point that may cause metal fatigue over time, which may lead to total failure.
