Boy, do I love this Fosmon set. Not only does it come with a charging station, but batteries as well! The NiMH battery packs charges quickly, as advertised, at about 2-4 hours. Depending on how much rumble you use, it CAN definitely last for 28 hours of active play time! You can also leave it charging on the stand because once it detects a full charge, it will leave it on minimal charging, so that you don't have to worry about overcharging your controller. However, I don't like to leave it charging. I don't leave ANY of my devices charging longer than it has to. It just kills the battery quicker and I'm just paranoid about overheating and ruining my controllers. It doesn't overheat though; I'm just saying. It's one of the easiest installation I've ever done. Just pop open the battery pack into your controller, plug in the charging station, and set your controller on the charging station. The BEST THING about it is how easy it is to just set your controller on to the charging station - NO CABLES to plug into your controller (but you still have to connect it to your charging station, of course). Not to mention how neat it looks on your stand. Awesome, stable, stylish, convenient, and one of the best bang for your buck!
