At this point Logitech's gaming mouse lineup is extremely well rounded. They have a mouse for just about every price point and gaming style. Some of you might remember back in the day when all they had was the G5 and later the G7 for gaming mice. The design of the G5 has carried through into a lot of their current day mice, especially the G400s. At a first glance the G400s has carried on with the same design that made Logitech gaming mice so popular back in the day. Today I?m going to take a look at the G400s and see how well that design is holding up compared to competition as well as Logitech's own product line.
