The Logitech G440 is one of the best mouse pads ever !! Only the price is a bit expensive. But for 30 euros you get a solid and very high-quality processed mousepad. Even when heated gamer sessions it remains fully in his spot thanks to its rubberized bottom. The coated hard plastic surface makes the mouse glide formally. However, the G440 is not too smooth. The surface is slightly rough to the sensor of the mouse to give the best conditions for a precise work. The surface of the mouse pad can be easily gereignt if necessary with a wet rag.
With my Logitech G 502 Proteus Core gaming mouse I'm perfectly clear on the Logitech Gaming Mouse. It is recommended that the G 440 profile in the Logitech Gaming Software select so that the mouse can feel at home.
