After using Reflex for a year, I've sold it and purchased G3. Without going into details, I will say I think G3 is MUCH better. It offers SO much more than Reflex. Needless to say I was even more surprised to see that it also supports NaturalPoint's Track IR device, and it works great! Kudos.. that's great programing.
Now, I just wonder why no one's mentioned it in all the RC sim threads I read prior to purchase??

I guess if you're not a flight sim fan also, you might not know about Track IR.
