What customers say about "Key Specs"
Logitech G900 Chaos Spectrum Professional Grade Wired/Wireless Gaming Mouse
  • Buttons feel solid, ambidextrous without sacrificing comfort in either hand, tracking is amazing.
  • Ambidextrous buttons and it's fully modular, whether you're right handed/left-handed
  • Awesome sensor, wicked response time and cable free!
  • It has the best sensor currently made for mice, and an entirely new and excellent switch design for the left and right mouse button.
  • I'm a hybrid grip style between claw and palm. The buttons on the left seemed too far forward for me particularly but this is purely based on my hand alone, not yours.
Logitech G903 LIGHTSPEED Lightspeed Gaming Mouse
  • Very accurate (PMW3366 sensor) and very smooth movement (I'm using a "hard" mouse pad).
  • No noticeable lag. It responds like a fast corded mouse.
  • DPI sensitivity adjustments can be quickly made on the fly (200 to 12000 dpi).
  • Wide range of polling rates (125 to 1000 per second).
  • It's clunky. Bad, poorly designed interface. Does not play well with High DPI settings. Slows down the computer drastically.
  • The scroll wheel sometimes scrolls backwards, or in the opposite direction intended. If you try to scroll down, it will sometimes counter-scroll upwards. As you can imagine, this is extremely annoying.

What customers say about "Size & Weight"
Logitech G900 Chaos Spectrum Professional Grade Wired/Wireless Gaming Mouse
  • The ambidextrous shape and feel of the mouse is perfect for my hands. Although the back end comes up a little further than I like, doesn't take long to get adjusted to. Battery lasts me a good bit for as much as I game.
  • Surprisingly lightweight, with great static-moving friction differential that's even better than advertised with a quality gaming mouse mat.
  • Very light weight for a wireless mouse. (about 107g)
  • Not really a con, but the mouse feels slimmer and longer than some other mouse, like even the G502. need sometime to get used to it.
  • I never got used to the "feel" of this mouse, It never disappears in your hand. It is a heavy mouse, too, so you know it is there.
  • While the technical specs. have be impressive, the ergonomics of this device is bottom of the barrel. Caveat emptor if you have larger hands.
Logitech G903 LIGHTSPEED Lightspeed Gaming Mouse
  • Nice weight (not too light, not too heavy). I did not feel the need to use the optional 10 gram weight.
  • The mouse fits comfortably in my large hand.
  • Ugly appearance. It looks like Batman designed it. The ribbed gaps of the primary buttons look horrible.
  • The length of the mouse is too long for users with small hands. And the side buttons could be farther forward.

What customers say about "Connection"
Logitech G900 Chaos Spectrum Professional Grade Wired/Wireless Gaming Mouse
  • Sturdy cable and connector, looks like it'll be quite durable
  • Wireless is on par if not better than the wire connection.( I prefer wireless over wired in games and productivity 9 times out of 10)
  • Connection and software setup is pretty simple-at least coming from the MX 700s (which is detected and used by the software as well).
  • It operates wirelessly with a very fast polling rate and has tested out again and again to have virtually zero lag regardless of the environment.
  • Even wireless this mouse is said to have less latency than wired competitors
Logitech G903 LIGHTSPEED Lightspeed Gaming Mouse
  • Logitech includes a small USB passthrough which connects the cable to the wireless receiver to make accessing the charging cable easier.
  • When the battery runs low I can just connect it via the USB cable and it instantly becomes a wired gaming mouse.
  • Can be used as wireless or wired.
  • Battery lasts awhile, easy to switch between wired and wireless, nice weight and fee

What customers say about "Features"
Logitech G900 Chaos Spectrum Professional Grade Wired/Wireless Gaming Mouse
  • The RGB is actually useful, as I currently use it to display different colours for each profile. Blue for General / Browsing, Green for Production, Red for Gaming
  • Amazing DPI Light and Logo RGB effects
  • Unlike other mice that have sensativity adjustments on the mouse these are hard to accidentally hit
  • Awesome battery life but can still be used while plugged in and charging.
  • Battery life is a blatant lie on the box. If you disable the onboard lighting the mouse onboard lights turn on and stay on during sleep/standby or off situations running the battery down uselessly.
  • Logitech Gaming Software is bloated, heavy, and can even cause Internet connectivity issues (!!) with more fragile LAN connections in Windows Vista/7 setups, which has been a known issue for years. Thankfully, not necessary for this mouse to work a full performance.
Logitech G903 LIGHTSPEED Lightspeed Gaming Mouse
  • Up to five user configurations can be stored in the mouse memory.
  • The side buttons are mounted high enough that I rarely hit them by mistake (I have all four active).
  • RGB lighting. The mouse lighting can be synced with the PowerPlay mousepad lighting.
  • It has lots of buttons, and those are programmable.
  • All buttons on the mouse click VERY LOUDLY. This is one of the loudest mice I have ever used!!!
  • The rechargeable Li-po battery is not designed to be replaced by the user and Logitech does NOT sell replacements.
