A must have for all Nintendo owners
Nintendo has a habit of using a proprietary screw head abnd this triwing is the answer for it. Open gameboys, gamecubes, wiis especially to service or clean or just explore. Furthermore Play-Asia is the most convenient place to get it.

Used one to fix 3 nonfunctional gamecube controller and get two of them to work...

Great item
If you would ever have have a problem with your Gamecube Controller, this is the thing to buy to open it up and clean out the inside to make work proper again.

Good Quality
If you're looking to get inside any recent Nintendo product, whether it be for repairs or modifications, you're going to need one of these. It has a magnetized like mose screwdrivers which helps to remove screws and to hold screws in place when inserting them. I've used it to get into my Wii, Wii Remotes, Gamecube Controllers and Wii Classic Controllers and it worked great. The one I received has a clear and blue handle and isn't abnormally shaped as the image shows.

Perfect
Used it on my GCN Wavebird controllers and Wii-motes best tool ever.
