Bought 6, all tested. None of them work when pushed all the way forward or all the way back. I'm wondering if those are discontinued parts or something because they're all clearly defective unless they've been adjusted 90 degrees clockwise or counterclockwise with respect to dual shock 4 (maybe there are other options DS4?). They should remove PS4 from their title or add a disclaimer. If you decide to buy it, you have to make sure that the blue part that sticks out together with the clicker is facing up or down, otherwise it will not work properly.
