A review of the Nyko Wireless Sensor Bar for the Wii - (or) - How to use the Wii when it isn't near the TV.

First it is important to explain what the sensor bar really does in the first place. The sensor bar doesn't really "sense" at all. Instead, it emits infrared lights from the right and left side of the sensor bar. The wiimote "reads" the infrared from the sensor and sends that information via bluetooth to the Wii console and thus tells it where the Wii remote is pointing. Thats about all it does. The cord going from the Nintendo Sensor Bar to the Wii powers the IR lights on the sensor bar.
I considered making a diy sensor bar with the help of this site or modding the original sensor bar like this, but it looked like more work then I had time for so I decided to buy the Nyko Sensor bar for $20 at Amazon. It was just too cheap to not try it!
The Nyko Sensor Bar comes packaged in a plastic tube

The Nyko Sensor Bar looks similar to the Nintendo's wired sensor bar except it is a bit bulkier, has a battery compartment on the bottom, a switch on the back that tells it whether to auto-off after one hour or two hours and a button on top to power it on. When its powered on, a blue led light glows on the front. The wireless sensor bar is powered by four AA batteries and Nyko includes a set of four batteries in the package. Nyko says it will allow up to thirty hours of use, but I wasn't able to test the play time (although it didn't run down the batteries after several days of play). Once you press the power on button, it will run for either one or two hours depending on the setting you select with the switch. Once it runs for that period of time, it begins beeping and flashing to warn you it will turn off soon. To avoid it turning off at this point, you press the power button for another hour or two of use.
Below is a photo of the Nyko Wireless Sensor Bar in front and the Nintendo Wired Sensor bar behind. Notice the IR lights on the left & right of the wireless sensor bar. These lights only show up in a photograph and can't be seen with the human eye. The bright blue led light close to the right side is the power on light
This is the bottom of the wireless sensor bar. The compartment for the AA batteries is found here.

On the top right of the wireless sensor bar is a power button and speaker for alerting you to a pending power off.

I highly recommend the Nyko Wireless Sensor Bar for anyone who needs to have the sensor bar and tv screen to be far away from the Wii console. The price is right and it does exactly what it's supposed to.
