I doubted for a long time to buy / not to buy this mouse, I didn’t want to catch double clicks, both LMBs were soldered on the existing 2 pieces of G600, and on one RMB to new switches, and according to reviews, this mouse will also have to install new buttons over time. In general, I bought a mouse, now I am "rejoiced". First, it is very comfortable for my hand. Secondly, there are no wires and you do not notice a difference in performance, thanks to Lightspeed from Logitech. Well, then, conveniently located main buttons, everything is at hand, but there are questions about the side buttons: On the G600 they are located much more conveniently, here it is convenient to press the first 4, but not the last 2. Too easily pressed right button, which I constantly zhmyakayu with inaccurate movement of the rodent also raises questions. In general, the impressions are excellent! It's worth it to buy it, it cost me 5,000 on 30/01/21 with the spent bonuses. For 7000 I would still think if it's worth it
