sadly your dual sens back button module may not last long it may have delay and in some cases if it doesn't work it's broken this is not the only issue with Edge we had rubber grapes peeling off and stick modul was being unavailable for a long time but there are two fixes if your controller has a warranty send it back and ask for a new controller the second fix is the back button modu replacement from extreme rate they did send it to me for review and I did not get paid my dual sens back buttons were working fine and still weren't broken yet I occasionally noticed that from like 20 presses one of them may not work or sometimes it's delayed I replaced the back button module with the video guide it was my first time opening dual sense Edge and if you are someone like me good news it's not that hard even for an average user you just need to remove back and front shell open the backboard and remove the battery afterward you replace the back button modual with all said it took me 40 minutes to do while I was recording the whole process by the way they provide extra screws and parts in case you miss them and I like that as you can see my old module looks a bit scratched and I forgot to tell you it was also glossy while the new one is matte the quality is very good even though my back bottom module wasn't broken yet once I replaced it and started testing it in multiple games such as code OverWatch and some other games I noticed improved performance and no lag every push counted the input delay is the same as a new controller when it comes to signal to console response however the physical responsiveness is now much better on my controller but how long does it last and where to get it from we need more time to test it I hope it lasts more than the OG model you can use the first link in the description or comments and order this modu kit from extreme rate if you use my code danad you will get 10% discount and I will get some profit thanks do I recommend getting this if your current module is fine if you sometimes feel more delay or it's not responsing to some of your pushes it's better to change it before it fully breaks but if you're not a competitive gamer and you play for fun you can wait until it fully breaks and then change it aside from stick modules if you're looking to give your controller a new look replacing the rubber grip ports and the glossy front shell maybe adding new th Caps or fully replacing every part of your dual sens you can check my other videos on the screen
