I used to use the exact same PlayStation back button attachment and was super bummed they didn’t make one for PS5. I didn’t feel like dropping $200+ on a Scuf or Battlebeaver so I found this on Amazon and it’s incredible.

I was intimidated at first because I’ve never really taken apart a controller but I followed this tutorial and just went step by step and it was easier than I thought. Took me about 20-30 minutes.
The paddles have been really stable and super easy to map. I use left paddle for jump and right paddle to crouch.
I’ve been using them for about 4 months now and I haven’t had any issues.
