With my setup, the Wii console is quite far from the screen, making the Nintendo-supplied bar impracticle to use.
Having a wireless bar should solve exactly this issue.
I chose this bar (Nyko) because it promised good distance (25ft/7.5m) and good battery life.
In reality, the distance is limited to no more than 13ft/4m - which i more than 40% off what is stated on the box.
Further, the bar has difficulties switching off (hold the button for 3 secs, the light goes off, let go of the button and it comes back on again!) which causes huge consumption of battery life. (i use rechargable, but it is still unacceptable.)
poor product. poor design.
