I bought a mouse for 478, in principle I am satisfied. Has some pros: - Convenience to hold in hand, because of the rough surface, if you wipe with a fleecy cloth, the villi remain; -Rubber pad on the left side of the mouse prevents the hand from slipping off, the surface is slippery and rough; - Choosing the number of dpi (affects the speed and response time, the lower the dpi, the higher the cursor speed, but the lower the response speed and the more dpi, the lower the cursor speed, but the higher the response speed); -3 additional keys; - Additional rubberized legs for "sliding" on the table; - It is convenient to play games, responds well; - Price Got cons: -Dust gets under the rubberized legs due to the fact that the recesses are wider than the legs themselves. No matter how annoying, but All the same, the fact is frightening; -Gap between buttons, gaps on the mouse. Dirt collects in them, a month will pass, clean it and play again; -Sometimes the palm sweats if you hold the mouse tightly.
