OK, I got three of these, one in Black, one in Blue and a Pink one. So all three kids got their own controller (yes one is a girl and it might be stereotyping but she is happier with the Pink than a plain White one apparently) and they know which is their own so it avoids some arguments. As far as I can tell they work just as well as the originals and whilst they have a slightly cheaper feel to the plastic we are talking about a game controller not an expensive fashion item.
They possibly get through batteries slightly quicker than the originals although that is probably because the kids use them more. However, I have a stack of AA rechargeables these days so there is not a problem.
At a considerable discount over the official controller and with no apperent drawbacks why wouldn't you get one? and the choice of colours is a bonus.
I brought two of these controls and having read reviews on other website i was concerned they would not work together (as some people have said they work on the same frequency). I tried them out with my two offical controls and they worked fine! Obviously for the price the quality is not as good and they are lighter and more plasticy then the officials, but they work and thats the important thing.
The only real let down with them is the speakers are not so good, sometimes not much sound and crackles quite a bit.
Overall considering they are over £10 cheaper then the officials i think they do a perfect job as additional controls for friends and family!
For the small price, these Wii remotes are ideal for easy games. But if your wanting to use these for more advanced games then beware...I've been playing Tiger Woods and compared to the Original Wii controllers these cheaper versions are not as responsive...Early shots taken and hardly no movement registering untill your swing is nearly behind your head..But all in all these are good for everything else...You'll pay for the price lol. The size of the unit is exactley the same as the Original, so all the covers and what not, fit perfectly......Oh and another thing...the "super heavy duty" batteries which are supplied with this lasted 3 hours lol...
