1PCS New Replacement 3D Analog Controller Thumb Stick Thumbstick Joystick for Playstation VITA 2000 PS Vita 2000 PSV 2000

I took apart my PS Vita to swap the analog thumb sticks with these new ones, hoping it would rectify the issue I was having of upward phantom movement on the left thumb stick. I replaced both the left and right sticks, put the unit back together and powered up the system. They did not work, they were not recognized at all. I opened up the unit again, put in the old sticks and they worked but I still had the phantom movement on the left stick. I decided to take the unit apart once again to try the "new thumb sticks" only to end up with the same disappointing results. On top of that, as if non-functional junk sticks wasn't enough, these things feel super cheap and the edges are almost as sharp as a bloody razor. If they did work, I don't believe I'd be able to use them without injuring myself. Don't waste your money, but more than that don't waste your time!
