Why didn't Nintendo release the Wii with this level of sensitivity in the WiiMote?!
This device makes gameplay so much better than before. It's a little disappointing that you require it to play some games (hence the purchase) but to be honest it's such an improvement over the old controls. There are still a few "low speed" sensitivity issues, such as putting in golf, but across the range this device makes the Wiimote 100% better.
Admittedly this item is pretty pricey (as there is NO Wiimote, just the addon) but that's to be expected from officially released items on any console.
It's a very nice gadget and does improve the game, but is very annoying that you have to splash out on so many Motion Plus's on games like Wii Resort Island where you have to have one (or more if you want to play your friends). But for things like Virtua Tennis and Grand Slam Tennis, it's good because you can use it with or with out which gives you time to save up for more or gives you a chance to play your friends without one. But it is a great bit addition but I suppose my moan is at the games instead off the wii motion plus, but it would be nice to be cheaper.
I've got two of these for Wii Sports Resort and from the minute I used the remote for the main menu, I could feel a major difference in the accuracy. You can even play it from a further distance compared to the normal wii remote signal, but be warned because there is one negative point to make - using the WM+ drains the batteries twice as fast as normal so if you haven't already invested in a Wii charging dock then I would suggest it otherwise you will be having to buy new batteries every 2 days.
