Not long after the Wii launch, I went to Target to try to buy a console. They didn’t have any. They didn’t have many Wii accessories. They did have silicon skin grips. I doubted that they would make a difference with regards to the grip, but I figured they would be useful for color-coding the Wiimotes.
The first time putting the skin on was an ordeal. The skin is literally skin tight. Since the buttons aren’t flush against the wiimote, they impede the process. It’s also a hassle having to remove them when I need to remove the battery cover for syncing or for changing the battery.
However, I think it’s worth it. Superficially, it helps to know which wiimote is which so I can use one consistently until it is low on batteries, at which point, I know which one is low on batteries. Also, now that I am used to using the grip, the “naked” Wiimote feels relatively slippery. I definitely feel more secure holding the Wiimote with the grip.
