This product and this one : 8811787 are quiet similar i can see as main difference that the one on this page is for rights hands and the other one for both (left and right). According to the indications, got the same sensibility.

However, this is puzzling. Especially as the descriptions and the specifications are partly incorrect (both models are for right-handers and both have the same programmable buttons). The Swiss Logitech website only lists a G305 with the manufacturer number 910-005282, but not a 910-005283. I bought the G305 Lightspeed and it looks exactly like the G305 except for the G305 lettering on the bottom. The specifications of my G305 Lightspeed are identical to those of the G305 except for the information on the light sensor, which is stated at Digitec as "light-emitting diode" for the G305 and "laser" for the G305 Lightspeed. I assume that they are just different series of the same model.

It is the same product. This is an error. Please order the product Logitech G G305 (Wireless)

The difference lies in the mouse sensor: one is optical with a laser and the other optical with a light-emitting diode.

I had no problems with this mouse, even drag clicking works perfectly. However, since this is the first "good" mouse I bought, I can't really compare it with others.

It goes into sleep mode. As soon as you move it, it wakes up again, you don't notice any lag time.

quite possibly. in any case, there is a software with which many things are open to you. unfortunately, I can't tell you exactly.

The wheel (mouse wheel) is rubberised, the rest is all plastic without rubber.
