I ordered 2 sets to accommodate users in the family...was very tight on the wii motes. Then when attempted to use them would not allow the sensor to connect to the wii system to use. So, this was waste of money...i should return but we had already thrown away the packaging because ew were soooo excited to try them out.

The first problem is that there is no opening for the infrared so you have to pull the controller out to navigate in the menu and it is not easy to get the controller out. Secondly, these are very small, much smaller than others I have seen. Not worth even using them. Better off just using the controller.
