Brand new replacement laser for Nintendo Wii game consoles.
Laser diodes have a lifespan similar to a light bulb - the more it is used the weaker it gets. As the laser dies the Wii will begin having trouble reading game disc; some discs will play, others will get the "Can't Read Disc" error. Eventually the diode will stop working completely.
This replacement laser should get your Wii up and running again.
