O.K.
I was gifted my falcon from Altec after he won it. <3 altec
Falcon w/ Pistol Grip (No orange box)
Pros.
Well built, very sturdy, does everything it advertises to do.
Easy to configure, control and understand.
Fun game pack (kids and I both loved it)
Even my kids can control the Falcon with ease (6yo-12yo)
Excellent responses in games (push, pull, weight, texture, recoil, weightlessness, and being hit).
Heavy enough that the recoil and other effects do NOT slide it around my desk. Good design on the physics there

Good tutorial, very thorough.
Games Ive Tried:
Left 4 Dead
Crysis
Half-Life Series
Portal Series
Team Fortress
Cons:
Pistol grip is definitely not made for a woman or children. I can grip the trigger fine, but struggle to reach the buttons.. maybe if they were a little bit lower on the grip could i reach them with my thumb.. either that or a little thinner in the grip perhaps.. Kids had the same issues. We had to kind of contort our thumbs to reach buttons in heavy combat. If I let go of the trigger and move my hand JUST a little I can reach it.. so.. I'm thinking a thinner grip (across the side not the back) would probably fix this issue the best. If you are thinking about remaking the pistol grip.. May I suggest a three button on the back of the chamber? Perhaps compressing the slight hangover of the chamber and making that a little wider to accommodate for the buttons? If you want a drawing of my idea let me know, I can create it in photoshop.
Attachments aren't exactly SNUG on my falcon. I don't know if that's just me or not. I noticed it the most when using a shotgun and the tank in Crysis. My grip began to squeak so I stopped for a moment to check if perhaps my recoil was too high (even though it was all on normal settings) I had a gap in between my Grip and the Falcon

! It was in as far as it would go. If that's normal.. let me know. I would think you would want that thing tight considering the forces exerted. But in the same sense I can also see wanting a little bit of slack to reduce tear on the attachment's locking mechanism. I only noticed it because it was creaking, so it worried me a bit.
Other thoughts:
I know you are still in developing the mods and .dll files to allow for the falcon in game. I was wondering what games you had considered developing the library files for?
I would LOVE to try this thing in the Call of Duty series, the Battlefield: Series, Borderlands and Mass Effect Series.
