I appreciate the built-in LED display, which accurately reflects the charge level with the touch of a button, and the ease of charging with the included USB-A to USB-C adapter. These compatible Xbox controller rechargeable batteries slot in easily, and the included plastic covers are designed to work with newer Xbox Series X|S styled controllers. Alternatively, you can use the included plastic covers for Xbox One-style controllers. So far in my testing, the charge levels appear to hold and exceed those of my OEM Xbox rechargeable batteries, so I'm pleased with the performance. The LED charge indicator, which is visible at a glance, is excellent for ensuring I don't find myself mid-game with a depleted controller. An easy recommended buy, given the under $25 price for the two-pack and its performance out of the box.
