Just okay, very disappointed.

It is true that the sensor accuracy is outstanding and it is very nice in hand (if you have a big hand), but hey, autonomy is rather low (enough for the casual player but the big player LAN will likely have to interrupt to move in wireframe mode) and devastating ergonomics.
Already, two large black buttons under the thumb (and sub ... Nothing, on the other side of the mouse) are unusable because too sensitive thumb side and too hard for the other fingers on the other side; these buttons are so poorly designed that Razer has scheduled a latch to lock the mouse and make it usable. The 4 small gray buttons are usable only on the side thumb easily, on the other it is rather difficult. As for the adjustable rear hood, it continues to grind and play, it's a little scary. By cons is true that the adjustable side is practical and well designed.

But it's even worse in software. So now, to pair the mouse, galley a little, we retry 2-3 times it ends up walking, it's not too serious but good considering the price of the mouse stomach hurts. Then stupid detail: the mouse will not turn off by itself when the dock goes out. Well, not always ... Do not forget to turn it off manually or otherwise the next day, more battery. And then, once you switch profile, the mouse lague 15 seconds. Same goes if you wired. Sometimes, when the mouse is removed from the dock, no matter how it reacts and it should be back on the dock so that it works again. I forget something? Ha yes, sometimes we want to change the profile but no, it does not. One solution: open the driver. And then I have not managed to resolve what profile the mouse is supposed to take a default ignition. I have found no explanation website the user manual or driver. As against the profile association has a program works.

The profiles on a cloud in place of the built-in memory profiles as in logitech? What a revolution! Clearly, your mouse will not function normally as your computer will not be fully turned on, and you must reinstall the driver on every computer (and every session course!) Where you go to enjoy the profiles! Oh yes it is on, it allows an infinite number of profiles (3 against average with an integrated memory). It allows you to put all the keys and macros you want on your 6 buttons. -2 In order to change the sensitivity, - at least 1 to change profile. 3 buttons and an infinite number of profiles so. It is on how we see inconsistencies in the implementation and how the mouse software side was deliberately botched.

In the end, it was a mouse gamer middle / low-end: beautiful, comfortable to handle, precise, but botched the finish. This mouse is thirty euros, no more, and when we see that razer sells at a price that makes it the most expensive mouse on the market today, it is unacceptable to serve us a piece of plastic on which has ignores quality. And for me it is a mystery that is so highly rated on reliable sites such as The Digital eg.
