Summary: Overall, I love this mouse. I am only on day 5 right now but so far I am really enjoying the mouse. Over time some of my complaints I may find myself just getting used to. I am coming from using a Razer Deathadder and the extra buttons I am finding actually very useful. Recently I have been playing games like Minecraft and Battlefield 4 but surprisingly the extra side buttons have been very useful whenever I need to hit any key that is farther on the keyboard than 5 or...
Pros: LOTS of buttons, Feels nice to hold, Don't have to clean very often (unlike the razer naga)
Cons: Sometimes I find myself accidentally clicking some of the buttons on the side whenever I am playing FPS games and I get startled. (This could be because I have stronger hands and its easier for me to press the buttons.)
Pros: Everything is working as it should. It got picked up right away by logitechs gaming software and feels nice in the hand.
Cons: Damage to teflon pads on bottom of mouse that make it so that you can not use it on carpet easily (not that that really makes a difference since I use a desk but i bought spares anyway). should come with new pads applied.
Summary: Chose this after my Razer Naga started acting up (left and right click buttons would double click randomly, and scroll wheel would scroll in the opposite direction randomly) This mouse is superior in just about every way. The main selling point for me is how little dirt and sweat sticks to this mouse. With the Naga I'd have to clean it every couple weeks. After 6 months this mouse looks brand new dirt-free, I've never had to clean it once.
Pros: Great build quality, Logitech software is amazing, Ring finger button is a nice bonus
Summary: I recently started playing tera online and wanted a mmo mouse this answered my need.
Pros: -logitech has one of the best macro software, -mouse improves mmorpg gameplay, -lots of keys on the mouse for keybinding/macro, -fits my hand perfectly (my hand is pretty big), -can change colour of backlights
Cons: -wouldn't really call this a con but the latest razer naga offers similar functions but with mechanical keys, -for the a mouse this is kind of expensive, its nice to have but not totally needed for mmorpgs
Pros: One of my buttons require more pressure (C17) other than that its a good mouse. I play wow, and I'm not completely used to all the buttons yet. I sometimes trip over myself trying to find the right button in a pinch. Very nice for healing, its more difficult to get used to as a dps class.
Cons: just my button that requires too much pressure. But for $29 I'm pretty happy with it. I only hope I can get used to having so many buttons and stop tripping over myself when I need something fast.
Cons: This might take a lot of getting used to. The thumb buttons are hard to distinguish and having the ring finger button makes it hard to grasp firmly. When I push a thumb button, I almost always push the 3rd button. You can just shut that button off I suppose, but the fast action of an FPS makes this a little too hard to use. I actually prefer a weighted mouse, but the lightweight may be appreciated by some people.
Pros: Good button configuration and back light options for the side G keys.
Cons: G10 and G17 keys don't work on the mouse that I received. All other keys were functional. Problem persisted after firmware update. Item shipped in a bag, but there was no evidence of physical damage.
Cons: Newegg sold me a faulty mouse made before Oct. 2012 (U77.00_B0012) - I'm not quite sure if Newegg knows this but several users also posted they have received this firmware version. Keep in mind that it's a hit or miss with this version and it CANNOT be updated. If you do recieve one like mine, RMA immediately or contact Logitech for replacement. Unfortunately, I had my mouse for more than 90 days and newegg nor Logitech will not honor their warranty.
