As I mentioned before, at first I really wasn't a fan of the
Battery Grip. As a whole, it's really not that bad a device, but it's the little things that bothered me. First, after you get used to them, the handgrips are comfortable, but in the time it takes you to adapt your hand positions you will have many hours of wrist pains. The grips also feel like they are digging into you palms at times and will cause some discomfort. I also would have liked some kind of an indicator to let me know when the unit was finished charging. I found this a real annoyance because it just feels like a guessing game when you turn the GBA on and wonder, 'Is it charged all the way?' At times, I found myself not wanting to unplug the device from the wall because I wasn't sure if I had gotten a full charge. Since I have a clear version, I can easily see the actual cells, and cannot help to wonder if MadCatz couldn't have shifted them over just a little to add two more cells to get a longer battery charge.
Traveling with the system can be a pain. The GBA isn't as portable when this device is in place, but it can easily be removed and put back on. If you're looking for a great gripping device, this is definitely one to think about. However, if you're looking for a battery device, you might want shop around before settling on this device.
