Featuring the PixArt PWM3366 optical sensor, useful between 200 and 12,000 DPI, as well as an ergonomic right-handed shape, we expected great results from the mouse, during gaming and general usage. We quickly found out that we were not wrong. The PWM3366 has gained quite a reputation from everyone that’s used it. Gaming in Company of Heroes 2, Battlefield 1 and PLAYERUNKNOWN’S BATTLEGROUNDS, movement immediately felt natural, with no noticeable acceleration or jitter, even at the highest end of the sensor’s capabilities. This is certainly an improvement over the already excellent HERO sensor in the G603.
RGB lighting is a must-have for a lot of potential customers, with some users requiring their workspace to look something like the Blackpool illuminations. While the lighting itself is bright and colours fairly accurate, the software lets this down a great deal. We would really like to see a few more lighting options from Logitech. The lighting does sync with the PowerPlay mousemat and other RGB-enabled Logitech equipment, however.

Comfort, as mentioned in the G603 review, is excellent. Logitech have clearly done their homework in this department, even adding rubber sides to the G703, for added grip. The thumb buttons are positioned almost perfectly while the scroll wheel is wide and provides a nice, tactile feel when scrolling.
Battery life wasn’t something we had any problem with, with a charge only dropping to 80% after a full day of use. The software provides an in-depth view to what is consuming the most power, a very handy feature!
Arguably the most important factor on a wireless mouse is the connection quality. We cannot fault the wireless performance, at all, even when the adaptor was placed around 2M away from the mouse. Logitech recommend a distance of around 200mm, using the cable and adaptor provided. Response times were of no concern and tracking felt smooth and consistent at all times. Bluetooth connectivity can be found on the Logitech G603, also using the same LIGHTSPEED technology; it would’ve been nice to see that carried over to the higher-end models for further compatibility.
