Review on Black Logitech G604 LIGHTSPEED Wireless Gaming Mouse - Up to 240 Hour Battery Life, Dual Wireless Modes, 15 Programmable Controls, Hyper-Fast Scroll Wheel by Ada Marna Maria ᠌

It is impossible to use. Nerves are more expensive. I will never buy Logitech products again and do not recommend to others. Different pros: Comfortable to hold in hand while working. The hand does not get tired. The wire on the table is not tangled. You can configure additional buttons for the thumb, which greatly speeds up the work. Used to work in MS Office (I'm not fond of games). Has cons: RABILITY OF THE LEFT BUTTON appeared from the first day. At first, occasionally, after two or three months - every tenth click. The usual confident click of the left button generates a double click with all the ensuing consequences. For such money, a high-quality microswitch could be soldered! At least the most important - under the left button!
