The hex key still does its job everywhere else - handily swapping out alternate components, tweaking the thumb rest's forward position and securing in the five six-gram weights in the rodent's belly. Still, Mad Catz warns users not to remove this screw, so tweak at your own risk. We found the mouse was still capable of a pivoting the thumb rest with careful use of a screwdriver, however. Update: We contacted Mad Catz about the change, and were told the mouse's pivot function was "removed" to lower the costs. This screw-swap is likely the device's largest fault, and while it's strange (and somewhat annoying), it's a minor inconvenience at best, though we have to wonder why the change was made in the first place.

Although the mouse's pinkie guard and the thumb rest's sliding mechanism still use standard hex sockets, adjusting the thumb rest's pivot resistance now requires the use of a phillips screwdriver. seems to suffer a slight disadvantage on the customizability front as well - although it features all of the same movable parts as its predecessor, the angle of the mouse's thumb rest can no longer be adjusted using the unit's included hex key. Still, the one-way rocker gets the job done we didn't have any trouble hitting any of our pre-set configurations in the M.M.O. This isn't a major inconvenience, as there are only four levels to switch between, but being able to step up and down was a bit more convenient than cycling through all four settings just to drop sensitivity down a notch. The standard RAT 7 mouse features a DPI adjusting rocker just below the scroll wheel, allowing the user to kick the peripheral's sensitivity up or down with a north or south toggle - the M.M.O 7 doesn't discard this feature, but instead swaps the bi-directional rocker for a standard button. Most of the new rodent's changes are welcome, but we couldn't help but notice a few minor tweaks that seem to detract from the device. A pair of ActionLock buttons hug either side of the mouse's horizontal scroll wheel, each toggling a constant input of their respective clicker when activated - as well as a mode indicating LED color change on each button's edge. Combined with the legacy buttons on the rest's top lip, these additions give a thumb access to ten toggles at any given time.

Flanking the 5D's sides are two additional toggles, as well as one more skirting the edge of the thumb rest's bottom. 7's new five-directional rocker still does the "sniper button" trick, but it also offers four more inputs over its predecessor. Here you'll find a familiar round nub that was once the RAT 7's precision aim toggle - the M.M.O. The bright color almost acts as a "what's new" indicator, drawing attention to the seven new inputs available on the mouse's thumb rest.
