Yes the Wii more!

The Wii motion plus to really possible to increase the opportunities and the sensitivity of the original remote. The movements are reproduced more accurately and many games now uses this addition.

It is an excellent initiative to propose this controller with the Wii Motion longer included. It used to perform a small operation to include the module on the Classic Controller, so we gain in ease of use.

The result is always good, I have not seen any improvement or degradation in the accuracy of the Wii Remote more.

We can only regret that Nintendo did not propose this model from the beginning!

In short, a recommended purchase for all new fans of the Wii. For older this is not essential unless you buy a new controller (the living room walls are just as destructive to our Wii controllers!).
The Wii is indeed more cheaper than the Wii Classic Controller added to the Wii Motion Plus.

And if you like the color of choice there:

Wii Remote Plus - White
Wii Remote Plus - blue
Wii Remote Plus - pink
