Review on Logitech G G603 Lightspeed Wireless Gaming Mouse, Black by Jnis Zels ᠌

Pros: As a mouse it is quite good. The main thing I like about G603 and before that G602 is that they work for almost a couple of months on one charge of one AA battery. The accumulators / batteries themselves can be used as weights: you can put two, but you can only one. Cons below: It worked for exactly three years and the left mouse button began to double sometimes. But it's still better than the middle button on the G602, which deteriorated after six months or a year.
