The "window" for the light will not be quite as spectacular illuminated as seen on the product images; the light is distributed very irregularly, what is seen particularly at room light and / or reduced brightness of the LED. The optical sensor on the underside (the "Laser") will not turn off when you lift the mouse.
The mouse wheel / middle mouse button will me not quite like, as it often happens to me that I easily andrehe if I make a middle mouse button click the wheel - who often click in the browser with the middle mouse button on small links should understand how that can interfere , The right mouse button I press also often accidentally, but it may be because I do not think the mouse properly.
The mouse works without any software, so also in assembling a computer. With the software you can configure the mouse and these settings are saved on the mouse so you do not need to reinstall the software in a computer change. The program works and is also available on the manufacturer's site in case of an incorrect language version, but sometimes you have to press buttons a second time and the window shifts each time you save the settings.
With all of the above weaknesses the mouse would get at least four stars from me. My main reason that I bought this mouse were the programmable macros, and the work is very limited. You can various things put on the buttons: Shortcuts, macros, multiple touch of a button and a few standard features like DPI change and reverse the browser, but with all the choices and some hours around tinkering I did not manage the mouse Alt + Tab ( Window AC) or combinations ähnlcihe teach. My diagnosis for detailed tasting is that the mouse buttons simply all the no letters or numbers are not recognized correctly. They can indeed put in the key selection and also record in Markos, but they are not executed when you press the mouse button, so if you record a macro in which you "Hello world!" inputs are obtained when running the macro "hallowelt1". However, a small concession I have to do, when the key combination function can be one of the three buttons only from a drop-down menu in the Alt, Ctrl, Win and Shift to the left and the right are selectable and they work really (so so something like Ctrl + C [Copy] works). I'm going for a stupid implementation in the mouse driver, which stores only ASCII letters and numbers.
But there are fortunately still a service, and this has on the package pointed out that you, the customer is very important and you drop them a note kindly to write, if you have problems because they a happy to help. The manufacturer's website there was unfortunately the wrong address, there came after a week not even an acknowledgment that the request has arrived. Then through the contact link on amazon I got feedback, and we wanted to free a new post and I can even keep the not fully functional mouse. When I nachgehakt again after two weeks, has apologized for the slow delivery, and I was asked to wait another week. As still nothing came they wanted to send me a new one, and I have received and tried just (after two weeks) ...
No, this mouse will play no special keys. Affirms my hypothesis that the driver programmer has tampered. After about a month I can thing of course is no longer return.
