Our Verdict

The Logitech G502 Proteus Spectrum was designed with one goal in mind – desktop gaming. It is a full-sized mouse that offers a lot of palm support, and comes a nice braided USB cable that is 6 feet long. The PMW3366 IR sensor it uses cannot handle glass or glossy surfaces, but on regular desktop surfaces, it is precise and sensitive.

It also offers a ton of customisation features. You can customise the 9 programmable buttons for 11 functions, or the built-in LED lighting that supports up to 16.8 million colours. And like many gaming mice, you can change its sensitivity and polling speeds.

The Logitech Gaming Software it comes with is essential to accessing all those customisation features. It also allows you to fine-tune the Logitech G502 Proteus Spectrum for different table or mouse pad surfaces. Everything you need to adjust the mouse to your exacting needs.

Some may gripe about its plastic build but it doesn’t rattle or creak. In fact, it feels really solid and more importantly – stable. Gamers who find the G502 Proteus Spectrum a little on the light side can use its weight tuning system to beef it up a bit.

We are not sure how popular RGB LED illumination is to you, but those who enjoy showing off their gaming PCs will love the fact that it allows them to choose from up to 16.8 million colours. Even better, they can sync the light and colour patterns with other Logitech G devices.

The Logitech G502 Proteus Spectrum also comes with a scroll wheel that not only supports vertical and horizontal scrolling, but can also switch between ratcheted and smooth scrolling modes. Just press the small button next to the scroll wheel to switch modes – it can’t be any faster or simpler than that! Unfortunately, the scroll wheel had too much inertia in its smooth scrolling mode, and was quite noisy in its ratcheted mode.

Other than the fact that smaller hands may find it hard to reach the DPI Shift button, we really enjoyed gaming with the Logitech G502 Proteus Spectrum. It is therefore our pleasure to award it with our Reviewer’s Choice Award. Congratulations, Logitech!
