I give this product only one star because the mouse was broken after about 1 month. For the first time before the mouse was finally broken, a few times did not respond the mouse. After I put the mouse back into the USB port again this went without problems. But now the mouse unresponsive after several attempts to repair it. I have it connected at all ports of the computer, it is not plugged in a USB hub but directly to the computer! To other computers did not work this! You can change the colors through the included software yet. Scrolling works only as a single function, but only in very strong stock movements and also a very slow motion! At first I was very convinced of the mouse and found them very chic. The only drawback was the software is not available in all languages. I am very disappointed with the mouse because it was unusable after one month. I could see the mouse and do not return again because the 2 weeks return period were exceeded. I have only guarantee on the mouse, but do not know where I send the mouse or should I turn towards me. I own the mouse since the February of this year!
I would not recommend you the mouse, among other things, due to the lack of a support! Accesses to prefer more expensive variant and since you sure that this is due to a few years and if not you have a good support and they can change! Thank you that you have read this review to the end.
