Design and Build Quality
The Logitech G703 LIGHTSPEED has a medium-sized body measuring 124 mm long, 68 mm wide, and 43 mm high. Its shape is classified as ergonomic, and its handedness is right-handed.
The shell uses ABS plastic with a matte finish. This gives the mouse a conventional gaming-mouse design rather than a compact, minimalist shape.
It has build score of 8.5/10. Its ergonomic shape is one of the defining aspects of the mouse, particularly for buyers who prefer a contoured body over a symmetrical design.
The G703 is therefore worth considering if you want a mouse designed around a right-handed grip rather than an ambidextrous shape.
Weight
The G703 LIGHTSPEED weighs 95 g, placing it in the Medium weight category.
This is a reasonable point to consider before buying. The mouse is not positioned as an ultra-lightweight option, so users who prioritize minimum weight may prefer to compare lighter alternatives.
On the other hand, the G703’s strongest scores focus on comfort and ergonomics rather than weight reduction. Its comfort score is 9.5/10, suggesting that its overall shape and handling are major strengths.
If you prefer a more substantial mouse with a contoured shape, its weight may be acceptable. If fast, low-mass movements are your top priority, consider how 95 g compares with your current mouse.
