Personally, I love it! It works great, and I get to set and customize all of my controls. Afterwards, I sit back in my chair, put my feet on the mouse-pad (as shown on the banner on the website). It's very comfortable. I have given it all of the default Halo 3 Controles (ex. RB to get into vehicle, up on d-pad to chat). It is awesome. I also replaced q with x, since that is what H3MT and other teams are using for Deployable Cover.
You can also adjust the sensitivity and speed of the cursor with this program. I love it!
