What is Reddit's opinion of eXtremeRate Textured Red Dawn Programable Remap Kit for PS4 Controller with Upgrade Board & Redesigned Back Shell & 4 Back Buttons - Compatible with JDM-040/050/055 - Controller NOT Included?

From 3.5 billion Reddit comments

I have these on one of my DS4s: https://www.amazon.co.uk/dp/B07RLSXWC2

The four buttons will map to regular buttons and with a tiny bit of soldering they will map to the touchpad click (but not to touch and they only recognise both clicks as a single input).

But the wireless PowerA Switch Pro controllers have back buttons as standard, which again can only be mapped to standard buttons. They also have a much smoother gyro than a DS4 (although no touchpad). Swings and roundabouts.

Why not talk about paddles? Four paddles cost $30 and little work. It is so easy.
