Eh? How come?

I wouldn't say wrong plug, but if you noticed on the WiiU, the adapters itself has 1 part small and the other part slighly bigger (The kepala I mean). Supposingly, what I did was tilt it downwards into the adapter and it works. If it still doesn't go in, switch it around. I'd show you if I could but I have no way of doing that.

nah. I now have more than 20 customers who use travel adapters for the WiiU. All are working fine.

Happy to have another user here owning one.
Any tips or recommendation of games you need, just fire it here.
I'll be here to recommend some games 

I import most of them from Amazon, it's very rare and hard to find. Some Wii games I buy from Kyo.
Wii remotes, if you want it cheap can try hunt for Wii Party U bundle, it includes a remote and the game, quite cheap.

I have quite a lot of Wii games collection myself and most of them are new but rare ones got it used.

Just as long as it don't go over RM 500.

Also, i have a Wii Classic Controller Pro for RM 80. White color only though. haha.

how expensive was expensive?

Check behind the game box and see if it's compatible. There will be controller icons of wii classic controller if it does support.

I know some that works like Mario Kart 8, Super Mario 3D World, Bayonetta 2, Sonic Lost World and Wonderful 101. Source? I just checked all my Wii U gamebox for you.
Take note that not all the games works. Wind Waker HD, Hyrule Warriors, MH3U, Pikmin 3, Nintendoland, Wii Sports Club, NSMBU and Luigi U doesn't support it.

Thanks guys, I wasn't sure if the box is referring to Wii CC or WiiU CC. Now I don't have to buy the WiiU CC for now.

I remember when I first got the Wii CC with the MH3 bundle, I hated it cos you have to hook it to the Wii mote for the signal and power but after grinding 100 hours with it on MH3, I grew to love it especially how light it is and the abuse it can take.

Not sure how much abuse the Gamepad can take especially playing games like Bayo2.

I notice some lag on the Gamepad when playing Bayo2 demo, is this normal? I was still very near to the console but was trying the off-TV mode.
