Some pros: Very cool and comfortable mouse. I've been using these for many years now. The hand does not get tired, the wrist does not hurt. Different cons: Lives for three years of active operation. Then something usually goes wrong. The wheel on the last mouse stopped working. Bought a new one.

Some pros: The functionality of the mouse, the start button, the back button, for me this is a big plus ➕, the wheel has the function of a button but works by pressing it to the right and left. With its cons: The adapter sticks out of the laptop for a long time, it’s not very convenient to put the laptop in a bag, it’s high time to make a mouse without an adapter with a BT module.

Has some pros: yes, it fits perfectly in the hand. ergonomics. it looks aesthetically pleasing, both the mouse itself and the whole set. i advise you to purchase. Got cons: material wear. the rubber on the sidewall peeled off after 5 years of operation. the back button started sticking.
