Has some pros: One of the cheapest mice with two ways of wireless connection Indeed, the main buttons are much quieter than conventional mice. Looks better than the pictures Packaging is not blister! Cons: Do not look for complete batteries You can't just get the receiver out of the compartment Noticeable latency at 2.4 hz compared to Bluetooth Potential backlash of the lid when it is frequently removed Did not like the sides of the mouse - more like gloss Side buttons "walk" Unpleasant sound on my desk when moving (regular texture), so a cloth mat would be very handy The price of quiet main buttons is an ordinary iron membrane instead of a switch, which is why when selecting some folders on the desktop, for example, the selection itself may be interrupted due to insufficient clamping force
