The mouse is a bit longer than most, but smaller than many of the 'ergonomic' mice. It fits my larger hands comfortably which many smaller mice don't.

Most gaming laptops have a “chicklety” keyboard. If you can’t stand this type of keyboard, your only real alternative is to connect a better-quality external model.

This is the case for most Logitech mice, but it's nice to get both options on such an affordable product, and one that also features multiple tunable buttons. The G502 also uses a handy LED-based DPI indicator for various settings—normal, fast, super-fast, and slow—so it's especially good for shooter scenarios where different weapons call for different optimal speeds.

Fortunately for the fiscally conscious gamer, there are some sub-$1,000 notebooks that can run graphically taxing games like Destiny 2 and Shadow of the Tomb Raider at solid frame rates.
