What do you know about that BT adapter? I've been looking for one for my M for a very long time.
It's a nice little gadget, works well with my CM Storm boards. Tempted to get TS's unit as a backup; $25 is a decent price
However when I hook it up to my M,
1) I can't get the NumLk / CapsLk / ScrollLk to light up (although they can still be toggled)
2) The battery dies after a couple of hours
