The Logitech G502 Proteus Spectrum is a very good wired gaming mouse. It feels very well-made, has plenty of programmable buttons, low click latency, and a comfortable right-handed shape with a thumb rest. That said, it's quite large, and while it's well-suited to all grip types, it's only suitable for larger hands. It also includes a set of five 3.6g weights if you'd like to adjust the center of gravity or add more weight, though it's already a heavy mouse. Unfortunately, the CPI range isn't as wide as those found on later versions, and our unit's sensor is inconsistent and undershoots the set CPI more during quick cursor movements than slow ones. There's also an updated version of this mouse called the Logitech G502 HERO.
Our Verdict
The Logitech G502 Proteus Spectrum is good for office use. It feels well-built and has a comfortable right-handed shape with a thumb rest and rubberized grips. It has plenty of programmable buttons and companion software for customization that's compatible with Windows and macOS. Unlike most gaming mice, it also has a scroll wheel that unlocks for free scrolling and has L/R tilt buttons. Unfortunately, it's quite heavy, it's only suitable for larger hands, and you can't use it wirelessly.

The Logitech G502 Proteus Spectrum is good for FPS gaming. It has low click latency, it feels well-built, and it has a comfortable right-handed shape that's well-suited for larger hands using any grip type. It also has a sniper button that lets you shift to a custom CPI setting while it's held. Unfortunately, it's heavy, its cable isn't very flexible, and the mouse feet don't glide well directly on desks. The sensor on our model is also fairly inconsistent and undershoots during fast cursor movements.

The Logitech G502 Proteus Spectrum is great for MMO gaming. Although it doesn't have as many buttons as dedicated MMO mice, all the buttons are programmable, and you can set a G-Shift button to enable a second layer of commands.

The Logitech G502 Proteus Spectrum is mediocre for fans of ultra-light gaming, as it's much heavier than dedicated ultra-light mice and its cable and mouse feet are only decent. That said, it has low click latency, it feels well-built, and it has a comfortable right-handed shape. However, it's quite large and is only suitable for larger hands, regardless of grip type.

The Logitech G502 Proteus Spectrum is the predecessor of the Logitech G502 HERO. The HERO has an updated sensor with a much wider CPI range, a lower lift-off distance, and less CPI variation. It also has marginally better click latency, though it's likely too small of a difference to be noticeable. On the other hand, the Proteus Spectrum has a somewhat lower minimum CPI, but its sensor is much more inconsistent and undershoots the set CPI more during quick cursor movements.
The Logitech G502 Proteus Spectrum is a predecessor of the Logitech G502 LIGHTSPEED. The biggest difference is that you can connect the LIGHTSPEED wirelessly with its USB receiver, and it recharges with an impressively flexible micro-USB cable. The sensor is also updated and has a much wider CPI range, a lower lift-off distance, and marginally lower click latency when wired, though it's likely too small of a difference for most people to notice.
The Logitech G402 Hyperion Fury and the Logitech G502 Proteus Spectrum are visually similar wired gaming mice with a few noteworthy differences. The G402 is lighter and has better click latency. On the other hand, the G502 has a wider CPI range and a mouse wheel that unlocks for free scrolling and has L/R tilt buttons. Both mice are well-suited for all grip types for larger hands, but if you have small hands and prefer a palm grip, you'll likely find the G402 more comfortable.
The GLORIOUS Model D is an excellent ultra-light gaming mouse, while the Logitech G502 Proteus Spectrums is more versatile. The Logitech has many more programmable buttons, a scroll wheel with L/R tilt buttons that unlocks for free-scrolling mode, and companion software compatible with Windows and macOS. However, it's much heavier. Comparatively, the GLORIOUS has a much more flexible cable, better mouse feet, and a more consistent sensor. Both mice are well-suited to all grip types but best suited for larger hand sizes.
