OK, you don't need this Nyko Charge Station unless you really want those grips on the back. I went to Wal-Mart last night to take a look at them and I got a much better deal. I bought a Rechargeable Battery kit for $16, and it came with 4 AA batteries, and 4 AAA batteries. I also bought 4 more AA batteries for $6. The total came out to be about $24 including tax. This is a much better deal. If you have 4 Wii Remotes, you will realize that this is a much better deal apposed to buying 2 Nyko Charge Stations, that would come out to be $60. Just make sure that when you buy rechargeable batteries that they are AA and Nickel Metal Hydride (It will say so on the package).
Just trying to help people out and help you save money. Also this is great because your not limited to using the rechargeable batteries just for your Wii Remotes.
