I have purchased rechargeable batteries and chargers for XBox controllers before. This was my first purchase of this particular brand/model. While it works for charging the batteries and I seem to get good usage out of the batteries before they die, the design of the charger is a little goofy to me. First, the controllers sit facing opposite directions. If the charger is in the middle of a table, that might make sense. If you have it against a wall, like I do though, the controller on the back side (toward the wall) is kind of a pain to work with. Part of the problem is that the units do not charge unless you push the controllers down and click or toggle the spring-loaded charging station. I suppose this is a good feature as it gives you a place to store the controllers (on the charging base) without actually charing them (which allows you to run down the battery over time before recharging them, which should increase the life of the battery, I believe). Along those lines, though, the recharging light is built into the base of the unit, making it difficult to see, especially for the "rear" controller if the charging station is pushed up against a wall. It is a challenge for me to see if the charger is actually charging as it is not easy to see the charging light. The charging light effect goes around the base of the charging unit, which would look nice, I suppose, if the charger were out in the open somewhere. Let's face it, though, a Xbox controller charger is not exactly the centerpiece of a typical living space and I suspect most will keep it tucked away. If that is the case, some of the features (such as the toggle function to charge and the location of the charging indicator light) are inconvenient or poorly incorporated.
Still, it works as advertised and, if those minor issues are not a concern, there is no reason to shy away from this particular model or brand.
