When we reviewed theour biggest complaint was that it required two AAA batteries. That aside, we really enjoyed the luxury of removing the wire that normal tethers your Wii remote to the nunchuk.
Nyko has responded to some of our gripes with the Kama Charge Kit, a rechargeable version of the Kama nunchuk that docks and charges in a special cradle molded for it. The kit also adds a rubberized backing to the wireless nunchuk--a feature we really liked included with the original.
In addition to storing and charging the Kama nunchuk, there's also room on the dock for one Wii remote to be charged, and Nyko has thrown in a rechargeable battery and gripped batter cover to boot.
While Nyko has yet to set a price, the Kama Charge Kit will ship to stores this April.
