Functionally, it works, it will power your Wii console. Once you pick it up and hold it, you realize it feels much lighter than the normal Wii power brick. I was actually suspicious when I first received it so before I even hooked it up I opened the case and took a look inside. It uses a very small transformer, I was actually worried it was too small to dissipate heat and could have issues in the long term, but it's worked for the last 40+ hours of gaming.One issue that is apparent (in dark scenes mostly) is a barely visible snow effect. Remember VCRs back in the day, when the tracking was off you'd get hazy snow moving across the image? The effect is similar but very muted. I attribute it to the small cheap components on the inside.A the end of the day though, it's been working for a few weeks without any other issues, so I'm giving it 3/5 because it's cheap and it gets the job done.
