Xbox saving One Elite Series 1 Wireless Controller

Product Name: Xbox saving One Elite Series 1 Wireless Controller
Microsoft Xbox One Elite Series 1 saving 1698 wireless controller. The controller originally had a broken LB RB button that was silver. I have taken the controller apart and replaced the RB LB button with a black one. The controller includes a case, 2 sets of paddles, 2 D-pads, and 3 sets of thumb sticks. The rubber on the handles is still intact but might be a little loose or not in perfect condition. Battery cover door is missing. Controller has been fully tested and works fine.
