GDA: Recharger station for Wii for $5 (plus $5 shipping)

This is going to be a YMMV kind of deal, but my husband just picked up two sets of these for Christmas presents. Kids love the Wii. 

From the website:

Nintendo Wii Dual Remote Charging Station with 2 Hi-Capacity Rechargeable Batteries - Recharge 2 Wii Remotes Simultaneously!

You’re in the middle of an awesome game, tension high, adrenaline pumping, and then… Warning: Low Battery!

Don't let the fun stop due to lack of battery power! With this Wii Dual Remote Charging Station, you’ll have everything you need for easy, automatic Wii remote charging and storage. In addition, FREE Rechargeable Batteries are included with this Dual Charging Station. The batteries can charge on the stand without your Wii Remote, allowing for longer game-play. The two battery packs install quickly and provide more than 16 hours of playtime with one single charge. Built into the charging dock are multi-colored LEDs which indicate charging status. The station’s design mirrors the Wii’s clean white aesthetic and will match your console perfectly.
