Yueton Pack of 2 Black and White Replacement AA Battery Case Back Cover Shell for Xbox 360 Controller

fits perfectly

Fits great, cheap replacement for old faulty 1st party covers, seems solid enough for the price. The color is a little off from the controllers, especially the white one.

These are not perfect fit. But they serve the purpose. Just press the locking system to help it to fit.

Just as described

For perfectly, and a great price
