I've been using it for over half a year now. The first days, when using the mouse, there was nowhere to put the ring finger and little finger, after a couple of days the hand got used to it. In general, I'm happy with the mouse. Has some pros: - Build quality - Laced wire, strong enough - Macros (although I don't use them, but still) - Appearance. The mouse looks really cool - Scope of delivery (There you will find stickers, a cloth for caring for the mouse, and even replaceable legs for the mouse). - Weight. For some, it will be a disadvantage, but I like it when the mouse is heavy enough (the weight can be unscrewed by disassembling the mouse). Has some cons: -Ergonomics. For quite a long time, the hand got used to the mouse, in the early days I even thought about replacing it, because it seemed enchantingly uncomfortable. (Individually, so I will not lower the rating).
