Hello all in the upper Cumberland. Just wanted to let you know that if you have a PlayStation controller (Modded) and your back button is not working. More than likely you've broken a pen and I can repair it more than likely. Send pics if it's disassembled if not let me know what's going on and I'll let you know if that's the issue. I can repair these $25 per side if they're both broken, then you know the deal. This is way cheaper than buying a whole new controller and these parts are not available for us to purchase. I have searched all over in PlayStation is not supplying these through the manufacturer of these items. I'm hoping down the road I can make a mold to make an aftermarket one. Mine is cast aluminum and repaired it better than it was. Just letting you know it was broken to begin with so if it's not fixable you've lost nothing at no charge. But I'm not had that issue yet.
