For the price, this sports pack cannot be beat. It is a useful and almost necessary add-on for any Wii system.
The baseball bat, tennis racket, and golf club share the same handle. The Wii controller fits into the handle. The handle screws onto each attachment. The protective clear cover on the controller must be removed first.
The baseball bat makes hitting much more fun. It's made of a lightweight plastic so it isn't even close to the weight of a real bat. (Which is a good thing for your TV). I still found myself assuming a batter's stance and following through on my swing. Oh, the controller must be removed during pitching. Not a big deal since it just slides out of the handle.
The tennis racket is sorely needed. It makes the tennis game much more fun. Stepping into forehand and backhand shots feels realistic. The racket was so much fun that I now play 5-6 games each time I fire up the Wii.
The golf club is nice but very short. I wish it had a little more length to it. Controller is about 2ft fully extended. Perhaps attaching a weight to the club head might help.
Haven't tried the steering wheel. Can say that the Wii controller sits in the middle of the steering wheel.
