Gear Review: Logitech G502 Proteus Spectrum Gaming Mouse

Oh how do I love Logitech’s G502 Proteus Spectrum gaming mouse? Let me count the ways!

1) Smooth Comfort: It starts with the multi-textured casing, which combines crosshatched, rubber-coated texturing on the sides–for maximum grip and control with the thumb on the left and pinky and ring fingers on the right–with a smooth, matte plastic surface covering the rest of the shell. The left side of the mouse is grooved with a protruding lip on the underside providing a platform for the thumb to comfortably rest on. The surface feel of the primary mouse buttons is great, too. The right button is convex while the left button’s concave contours form a natural, subtle valley that cups the full length of the index finger. Button placement is on point as well, all 11 of them laid out within immediate reach of one finger or another so you aren’t having to contort your hand in awkward positions to hit certain actions. Elongated forward and backward buttons sit on the left side, just above the thumb groove. Right on the tip of the thumb is the DPI shift. Angular DPI up/down buttons fall along the top left, just off to the side of the left mouse button for the index finger to get at as needed.

2) Flawless Tracking: Logitech’s Delta Zero optical sensor offers a DPI range of 200 to 12,000, with reduced acceleration and pinpoint accuracy and precision that never jitters, sticks, or lags behind. Buttery-smooth feet enable the mouse to glide effortlessly on a mouse pad or even directly across a desktop (depending on your desk’s surface of course). Using the included Logitech Gaming Software app, a DPI shift as well as up to five different DPI settings can be customized to your liking, and then saved in multiple configurations across up to three different on-board profiles. DPI levels and saved profiles can then be hot-swapped on the fly at the quick tap of a button. An LED light bar located between the forward/backward buttons and the DPI adjustment tabs offers visible feedback via three little windows that illuminate or darken as DPI is shifted or toggled, to always show which sensitivity level you’re set at (or which profile is selected). Each profile also can be saved with its own RGB lighting configuration, which is helpful if you like to associate certain color schemes with DPI loadouts for certain genres or specific games.

3) Reach Your Ideal Weight: A nice perk included with the Proteus Spectrum is a set of five tuning weights, each weighing in at 3.6 grams. The mouse’s magnetically sealed bottom face panel encloses a series of channels where the beveled, v-shaped weights can be slotted in around the optical sensor–there’s room to squeeze in all five, if you like a lot of heft. A small clamshell case comes packaged in the box for storing any weights that aren’t added to the mouse. With or without the weights, the mouse itself feels solid and durable and well balanced. The mouse buttons in particular are very clicky and tactile yet firm and reactive to the touch, like they are built to last through a heavy pounding. This isn’t an inexpensive mouse, but you totally get what you pay for in terms of quality design.

4) Hyper Scroll, Engage: Another small yet much appreciated feature is the mouse’s dual-function scroll wheel. With the push of a button (which is located right beneath the wheel) the wheel changes from a standard notched scroll style to a hyper-fast mode where the wheel spins freely and smoothly in either direction without the intervaled feedback bumps. Having the option to quickly swap back and forth between the two functions comes in quite handy indeed.

I’ve been rigorously testing the Proteus Spectrum for around four to five months now as my one and only mouse for gaming and everyday PC use, and not once has its performance wavered against any gaming genre or general computer task I’ve thrown at it. I can’t recall using a mouse as ergonomically comfortable and intuitive as this one, and I’ve played with a ton of mice in my multiple decades of gaming. The build quality feels solid and reliable, while the overall design is sleek and polished, making for a happy marriage between confident, durable functionality and enough flair to look cool without going too overboard on gratuitous flourishes.

I suppose the only potential stumbling block is the right-hand-only design. Unfortunately, lefties are plumb out of luck here as the mouse’s contours, button placement, and RGB lighting are tailored for use and visibility with the right hand. This is a wired mouse as well (braided cable!) so anyone in the market for a wireless mouse will want to consider other options.

Those minor points aside, at this price range you won’t find a mouse with a more finely tuned all-around balance of functionality, durability, comfort, sensor accuracy, and pure, blissful gaming performance than the Proteus Spectrum.
