To accompany the bare-bones price of the MX300 is a bare-bones layout. Identical in shape to their old Optical Wheel Mouse, the MX300 features a stylish black/silver colour scheme with a standard 2 button + wheel layout; but with an additional function key at the top as well. Like most Logitech mice, the MX300 is fairly heavy due to the small weight they placed in it. Whether this is good or bad is highly dependent on user preference, however.
