Don't get this mixed up with the 3rd party controllers that dealextreme also sell, this is a genuine Nintendo Remote controller. It does not come with batteries.
The Wii Remote is the Wii console's revolutionary controller. It contains a built-in motion sensor and communicates wirelessly with the Sensor Bar for unprecedented precision and ease of use. It also has a rumble feature and a built-in speaker to immerse you even more in your favourite games.
For those that don't know dealextreme, they are based in China, and orders typically take 10-14 days to be delivered(free).
You can pay by Paypal.
I've been using them for about 2 years with no problems.
If your items break, you can return them for a replacement, and they refund you the postage costs.
