What is this thing?

Is this a chinese knockoff controller?

lol

Terrible

It actually has a serial number and plugs into the tv with official PS brand av cables.

Sorny Paystration?

Looks like either a cheap plastic knockoff or, more likely, a 3D-printed. Though honestly I expect 3D printing to be better than this.

Pretty sure I saw that controller once sold at a Gamestop here. Looks more like a tv remote to me lol.

Take a picture of the serial number and connectors.

Where can I buy it?

So I have asked Ashens, aka the foremost expert of gaming hardware crap in the world, and he has immediately identified it as a PS3 Rock Band drum kit controller module. You can see a slightly different version of it mounted on the drums in this picture.

@Black_Knight_00: can confirm. I had it on 360 looks the exact same except for the Xbox colours.
