I have a problem (and it's not the Corsair mouse missing from the graphic, but it is!).....

My problem happens to be an inability to adapt to a new mouse. Which is weird. I upgrade my hardware all the time. New keyboards, new monitors, etc, etc. Yet my mouse....I am very picky about.

That's problem #1.

Problem #2 is fucking Logitech. Their new millennial designers are MORONS! If they knew what makes a good mouse or a bad one, people would buy more Logitech. Alas, Logi (how cute) is bottom rung, low brow, the worst. Such a fall from grace.....but.....the is another!

If you just want the final pick....like you have to ask.....the Logitech G602....IS.....the perfect mouse ever built! Read on for the comparison.

The Scoring	Logitech G602	Logi G502 Lightspeed	Reddragon M913	Corsair Darkstar
Size (subjective)	Perfect	Slightly to small	Frickin huge!	Slightly to small (although bigger than the G502)
Style (color)	The 3 tone design is good. Hard dark black and light silver plastic accents with black rubberized rest points	It's black. Shiny black, dull black, rubberized black.	It's black. Shiny black, dull black, rubberized black.	It's black. Shiny black, dull black, rubberized black.
Style (RGB)	No RGB	Mouse changes color schemes on it's own. Software is complex and not user friendly. On the plus, it does read from the software for the G13 and G602, when it feels like it.	Color change is solid. Static colors stay until changed. Dynamic ranges look pleasing. Because of it's size, more to light up!	Color change is solid. Static colors stay until changed.

Programmable Buttons	11	11	16	15
DPI sensitivity	Configurable through the software and and "on the fly" button for "sniper" mode.	Configurable through the software and and "on the fly" button for "sniper" mode. However the software changes the DPI without warning. With profile switching turned off, it still changes DPI when moving from windows to window (of different resolutions). The dedicated thumb button to switch DPI might work for FPS games, but for anything else it's annoying.	Configurable through the software and and "on the fly" button for "sniper" mode.

Power	2 removable AA batteries. Standard rechargeable batteries last from 2 to 3 weeks. Takes seconds to swap them out.	Internal battery. Lasts 5 to 10 days (depending on RGB usage) on a single charge. Can only be charged via cable. Defeats the wireless ability.	Internal battery.

Usage (subjective)	The mouse fits perfectly in may hand, although my hands are not particularly large. My Index and middle fingers rest almost directly over-top of the left and right (respectively) mouse switches. The weighted scroll wheel makes navigating large documents a breeze. While gaming, scrolling is quick and responsive. The push-button scroll wheel detent on/off is of great help. The side programmable buttons can be easily reached without moving my fingers from primary and secondary buttons. The buttons work without the configuration software running. The configuration software is simple and easy to understand and the software also controls the G13 Game Pad, other Logitech keyboards, and other Logitech gaming peripherals.	The mouse is small compared to most gaming mice. For example this mouse is smaller than the Coursair Darkstar. My Index and middle fingers rest slightly forward of the left and right (respectively) mouse switches. The scroll wheel is not weighted. You'll be scrolling for days on large documents. While gaming, scrolling is quick and responsive. The push-button scroll wheel detent on/off is of great help. The side programmable buttons can be easily reached without moving my fingers from primary and secondary buttons, but there are only 3 of them. The configuration software is terrible. The buttons are useless without the software, unlike the G602 and Coursair Darkstar. Meaning you must run the software to game with those buttons, taking resources away from gaming. The software a has a very convoluted layout. Nothing is intuitive. Changing button function is temperamental, it's simpler to disable a button then assign it a new function than assign it directly. The RGB function is also non-sensical, making no logic movements based on what the computer is doing. This mouse is a very expensive shadow of the G602 and Coursair Darkstar.	This mouse is huge! I was shocked at how big it is. All 4 of my right hand fingers can rest comfortably on this mouse! Because of the size, the left and right click mouse buttons switches are extremely far forward. You can not comfortably depress these. The 12 side buttons are a good size and spaced out. You can not depress these side buttons while using the left or right click buttons. I found the software confusing. No organisation of features. RGB features were pretty lame, so I left it on default red. The side buttons do not work unless the software is running, a major drawback. In short, a bad mouse next to the G602.	The mouse is a good size although slightly smaller than a G602. My Index and middle fingers rest directly over-top of the left and right (respectively) mouse switches. The weighted scroll wheel makes navigating large documents a breeze. While gaming, scrolling is quick and responsive. The push-button scroll wheel detent on/off is of great help. The side programmable buttons are TINY! You never click just one side button, but all the buttons in that quadrant. The configuration software is not bad. For to much focus on RGB, but if you just ignore it you'll be fine. The buttons work without the configuration software running. This mouse would be great if not for the tiny side buttons.
My Rating	#1	#4	#3	#2

I've come to the conclusion that all mouse manufacturers are not capable of making a decent mouse anymore! With Logitech abandoning the G602, I would hope someone would steal that market.

There is a small group 3D Printing a G602 with parts from China to mixed results.

Alas.....I shall stay on the path searching for the perfect mouse.
