In detail:
The first impression (before opening the packaging) is pretty good. The design is a bit daring, but it catches the eye. Packaging transparent plastic small effect and looks good mouse.
Opening the plastic cover, there is a manual (summary), a carrying bag (correct), a battery, and finally the mouse itself. And this is where the problems begin. Plastic does not seem to be very good to the touch, it is very, very fine - I doubt she would survive months of intensive use, but the future will tell. More importantly, it is brilliant. This means that as soon as you step out of the package, your fingerprints are everywhere above. A minor fault, certainly, but I use my mouse for only three hours ... and it is horribly dirty. Note
At ergonomics, size setting is nice, you can adjust the mouse (to some extent) to your hand, not your hand with the mouse. It's probably the best point for this product (with the laser, but I come back later). The placement of the buttons (except the right-click, left-click and scroll wheel) ... and disturbing. The backspace buttons and the zoom ring in particular seems to have been placed with a very approach "where the glue has room there." The zoom ring is simply unusable without lifting the mouse hand, and the back button to move forces the hand - then that is certainly (at least for me) the button that I use most except the buttons primaries. The middle-click is too hard (I thought for the first few minutes there was none), and makes a sound that gives the impression to be back in 1998 ...
The software (available for download on the site) is of acceptable quality. Nothing more, nothing less.
In use, there are qualities to the mouse, such as the fact that the Bluetooth dongle is not required if your computer supports Bluetooth 4.0. Teflon skates glide extremely well and mouse walking on my glass table, which no other mouse I've owned has done so far. In the game, the mouse has good performance (tested in Borderlands 2) the accuracy button (which slows the cursor) is nice, but not necessary (maybe multi players have a different opinion). The placement of the buttons as the other buttons can not really be used in the game, but it's not a disaster.
In conclusion, and as I said in the summary, the major problem of this mouse is that it is a fair product with low points, but at the cost of high-end mouse. There are so many better options for the price (and below) from Steelseries, Logitech, Razer, ... I do not see why anyone would want it.
