TrackIR's Track Clip Pro and the Duracell USB Charger (3hr version)

Was wondering if anyone has their TrackIR track clip pro configured to be wireless? I'm using a

velcro'd to the top of my headset. The things I like about this setup are, it's light, it's small and flat, it has an on/off switch, and I can just plug the USB charger/battery into one of my computers USB ports any time it needs a recharge. When I'm playing A3 the power from the charger to my track clip pro's LED's seems to last forever too. Oh yes, nearly forgot, did I mention that it makes the track clip pro wireless! :)

Mine lasts 8 hours mate. Same one as you have and only cost £10 from amazon, absolute bargain :)
