best nintendo controller
This controller is great. This is what the gamecube controller should have been. My advice is, sell your wii classic controllers and buy these as replacements, you won't regret it!

nothing beats Nintendo quality
If you want the best, this is the best. Got myself a pair of these, white and black. Not one regret.

Excellent product, but has rooms for improvement
Pros:
- More ergonomic than holding your Wiimote sideways
- Works with all VC games and many Wii games (Mario Kart, Smash, Geometry Wars, Muramasa...)

Cons:
- No rumble
- Needs to me connected to the Wiimote, meaning the remote need to be placed near your hands, on your lap, besides you, etc...
- No support for GC games

Very Good for VC
Bought this mainly for aesthatic reasons - Wavebird receiver sticks out like a sore thumb when plugged in on the Wii.

Excellent Nintendo build quality, works just like the normal Classic Controller if game does not support or need the extra buttons. And works fine on my Finnish / European console.

Better with more comfort. Still not perfect though
This is a really really good improvement over the standard classic controller. I never liked how much travel the shoulder buttons had on them, even though they were still digital. Now they have very little travel in them, just like how a digital button should be.

The overall shape makes playing most vc titles more pleasurable too especially for snes and n64 titles. Its not dual shock or 360 pad comfortable.

I still dont like the eight grooves around the analogue stick however and feel that that like they are forcing the stick into a fixed direction. It also has no rumble feature, feels very light and doesnt replace GC controllers as this controller will not work wil GC games.

Still worth owning for the improvements and if you have alot of vc titles. Hope that helps.
