The screwdriver can be removed really easy and during usage, when attached, it does not create any comfort issues:
With the screwdriver out, we can also remove two extra items in order to access the weights:
The weights are in a number of 5, six grams each; the M.M.O. 7 is not very light so people that have used cheaper plastic bodied mice prior to it may feel the need to remove them completely on the first stage:

The palm rests are easy to remove, by pressing on the orange metallic piece and pulling outwards, at the same time:
By removing the component completely, we can also discover that it can be placed in different positions:
The pinkie rests are also removable, by removing the center screw; near the right button, we can find an extra orange button, meant for the "shift" function, for doubling the functions of the buttons:
The thumb rest holds no less than 5 programmable buttons; the “sniper” button now can be moved in 4 extra directions, like a small joystick (Mad Catz likes to call this button 5D); in the same area we can find the second scroll wheel:
On the thumb rest we can also locate a Cyborg logo:
