I wasn't familiar at all with the Thrusmaster brand. I was skeptical because I have never had any luck with 3rd party accessories outside of Logitech products for my PS2. I did some online research, checking various places and saw that the overwhelming majority of customers were very satisfied. This controller is basically your cheaper alternative to the wireless Wavebird controller for GC and Wii.
The control has a sleek, clean and simple design. Its white with some wavy blue ridges I guess for better grip. Its pretty small though, so it will take time to adjust to if you're used to the Gamecube controller. The overall design and button layout is identical to the Playstation controller - 4 shoulder buttons, directional pad, 2 joysticks, rumble, etc. They give you 2 Z buttons I guess just to maintain that look of symmetry. You also have a turbo mode feature.
Response is spot on - instant. No lag/time delay. So regardless of the type of game, your commands will go through as they should.
The controller functions on 3 AAA batteries but luckily has an off switch to conserve battery life when not in use.
It comes with a signal transmitting device that goes into a controller port on your Gamecube or Wii. Its got a pretty sweet range too. Maybe like double that of the Wiimote's range.
You can use it for any Gamecube game or Wii game that supports GC or classic controllers - including Wiiware and Virtual Console downloadable titles.
The freedom of being completely wireless is its main appeal. Wavebird's are hard to find and the classic controller for Wii hooks up to your Wiimote to work so you'd have a wire to contend with. The miniature size and triple A batteries can
be a little annoying but overall for its price - £17.26 on Amazon - its a good bargain for anyone looking to save some money on a high quality controller.
