After two whole days of trying to accustom my hand to this terrible mouse, I was forced to take it back to the store and purchase a better option. Better for this money look for a mouse that is worth the money that you are willing to invest in it. With its pros: Of the advantages, I can only describe only the backlight. All. She can't do much more, unfortunately. Got cons: First: the distance of the mouse sensor (or whatever this laser is called correctly) to the mat (any surface) is about 1 cm. This is a lot: if there is not enough cursor sensitivity and you want to move the mouse more comfortably, then the cursor will fly around all the corners of the monitor - this is terribly annoying, both in crawling on the Internet, and in any games, be it a shooter or MMORPG or something else what other game. Second: the buttons are too big! I donโt know, maybe they were made with the expectation of giants, but even with my normal-sized hand, the fingers (index and middle) barely fit to make it comfortable for the whole hand, and when I right-clicked, my ring finger ached slightly under it, which was very annoying, because of the terrible design. I'm serious: don't be fooled by the beautiful lighting and supposedly cool design, as I was led. It's not worth it: another marketing scam. Lenovo, as it did not know how to make gaming mice, is unlikely to learn.
