Pros

Pro Comfortable for palm grip with easy to hit buttons
Great for palm grip along with a the fantastic logitech software for key mapping and profiles.

Pro Great battery life
Good for users that want a wireless mouse without any loss of functionality or need to change the batteries every week

Pro Good optical sensor
Only up to 2500 DPI but it's a great sensor for those that don't need very high DPI.
Pro Can run on single battery for lighter weight
Users can opt to run the device on a single battery to cut down on the weight but this will have an impact on battery life.
Pro Mouse wheel
The mouse wheel has a nice tire-like grip easy for scrolling through inventories or the internet.
Pro LEDs
For those with personalities, there is three spots of LEDs on the mouse the mouse wheel sides (which are strictly the colors of the different DPI settings), the Redragon Logo on the Palm area, and the 12 number buttons. The Logo and the 12 buttons can be programmed to change to countless different shades of colors. The LEDs can be set to a breathe function which I think is pretty cool to see in a dark room.
Pro Hardware macro storage
You can plug this mouse to a different pc without losing keybindings and macros.
Pro Lots of buttons
Great for MMORPG's, daily macros and professional software.
Pro Nice Surface
The surface of the Redragon Perdition has a nice grip-like texture that I find myself just plain rubbing at times. After 5+ hours of continuous gameplay, I don't find my hands slipping due to hand sweat getting on the mouse.
Pro Programmable Left-Left click button
Out of the box it starts out as a rapid-fire button, but can be programmed to anything.
Cons


Con Somewhat heavy
Being that this is a wireless mouse there is the battery weight to contend with. Batteries in the weight of the device is 152 grams, which isn't all that bad considering but still not for users that like a lighter mouse.
The mouse can also be used with a single battery, which is useful for not only reducing weight but also for balancing the mouse. With two batteries the mouse can be a bit slipper on the right side when picking it up as the pinkie and ring fingers don't have as much to grip - but balancing the weight over towards the thumb allows the mice to be more easily picked up as the side buttons allow for a decent place to grip.
Con No wired option
The Logitech G602 does not offer a wired USB option, only wireless.

Con Macro Key Defect
Side buttons are known to register multiple keystrokes occasionally when pressed only once. With bindings such as Ctrl+F4, this naturally has destructive results.

Con Middle mouse button wore out after a year of heavy use
And with no way to open it it's near impossible to fix.
Con Not suitable for FPS games
Lots of buttons = lots of missclicks
