evolution is not always good. Having to buy the previous model, the MX-2000 I can say that is good Perixx mice, they are configurable and sensitive enough to their price. The main difference with the old model is the number button, there is no longer the clique has the ring, are the two left and right buttons on the wheel, otherwise the "" button to change the dpi the old model that slid forward and back has been replaced by two real buttons, the button that was under the thumb of the old model was placed in front of this one which avoids inadvertent click, anti-slip rubber is better than the old model that had stripes and slipped a little at a vertical, the points of the new model have a better grip. The two big downside of this development is that the previous model allowed to browse the 7 predefined levels, the only 4 are programmable sensitivity level, by clicking in the management software on the number indicated, may have set 100 100 4 Levels from 100 to 5600dpi, the slider for adjusting this setting in the software is extremely hurt and imprecise, fortunately we can adjust via the box or dpi is indicated, except to the backlight for LED which indicates the selected profile dpi is green and can not be changed after the backlight of the knob and brand name are linked, you can change their color via a predefined color palette, brightness is not adjustable , it was on the old model. Otherwise smiled a synthetic rubber smell but its expected to rise.
Most: adjustable from 100 to 5600dpi -Sensitivity -the buttons 8 are reprogrammable (while the button may be changed in the software) -colour adjustable backlighting - The weight is adjustable (7 weight supplied) - The price
Cons: - The limited color palette, the non-adjustable brightness - Four sensitivity levels set, one must use the software to change the sensitivity level to which each level - Click (button) of the wheel is a bit hard
the price / quality ratio is excellent, although I find the model is a bit below are predecessor.
