In general, the mouse is chic, works without problems, is made of quality materials and is knocked down reliably, but these two drawbacks can significantly affect its liquidity. Got pros: Absolutely everything, except for two indirect drawbacks, I especially like the shape, which, despite its compactness, fits well in my fairly large hand Its cons: Mechanical buttons have a chance of double-clicking, unlike optical ones (but softer), you also have to buy rechargeable batteries, which weigh and cost a lot, which will already turn this mouse from 60 grams for 3500 to 68 grams for 4200
