I got the #AbxyluteS9 telescopic controller on Saturday and spent a bunch of time yesterday messing with it. I had a lot to say about it but since there is a dedicated place on Discord for it, I unloaded my opinions over there.
In a nutshell:
-Left Shoulder button is louder than Right Shoulder button
-If you press too hard on the d-pad it registers an adjacent directional input
-It turns itself off and won't fully turn back on unless you physically unplug and replug it.
Otherwise it's great.
