Bought this extra Remote Plus while recently buying our first Wii console, which included Sports Resort. I'd only played Wii for 5 minutes previously, using 1st generation controllers.
Based on all I'd read, the new gyro controllers vs. the old ones, my expectations were very high. Too high. While really very accurate and sensitive, in the big scheme of things, the controller will get disoriented when using a lot of velocity.
In other words, adults need to, say, swing a golf club more at a kid-speed, or risk complete inaccuracy. Same with other games...just don't swing too, too hard. Though I'll confess that the golf game was something I (Dad) was interested in! By the way, I don't know if this is possibly at least partly an artifact of the golf game's programming, exceeding its limits, or if perhaps Tiger Woods Golf produces a more 'accurate' swing with more velocity.
Otherwise, the controller has a decent feel, really nice rubberized cover, nice weight, easy to get at AA batteries, and it's not real bad on power consumption for those AA's, either.
So, swing like a kid, and you'll enjoy this product, whether bowling, golfing, or whacking each other with a sword.
