Summary: TL;DR: Adjustable lift-off feature is a gimmick and causes tracking issues that must be corrected by manually "re-calibrating" your mouse (even when Auto is selected). Razer used to be great, but they became money hungry and focused on impressing with form over function (form is great, but not at the cost of function). Full Review: I'm sad to report it appears that Razer is going the way of Logitech.
Summary: software that comes with this is awesome and I like how I can adjust the thumb buttons or the LED light up on the wheel and palm. It lost two stars because it feels too light. I like a little resistance with my gaming mouse and this doesn't have it. It needs a way to adjust the weight of the mouse so it feels like I actually have something under my hand.
Razer cords become faulty quickly at connection-point to mouse. 2nd model with this issue.

Summary: This is my 2nd razer mouse. Love the look, feel, and performance. However, this is the 2nd that has the cord connection to the mouse become faulty not long after purchase (the most recent of which, this one, happened after only TWO months of use). It disconnects and reconnects constantly with minimal movement of the cord (which is bound to happen when you are gaming with a gaming mouse...imagine that).
Summary: I love the feel and look of this mouse. However, like a lot of reviewers I'm reading, mine just stopped working 5 months to a year in. I liked the other aspects so much, that I have replaced it three times now and my third one is just now beginning to go the way of the others. The cursor will increasingly start skipping, stuttering, like it's thinking about something and trying to catch up... sometimes it will move on one axis, but not the other. I dunno...
Summary: Had the button start double clicking at holding when i was only clicking once. Took the mouse apart and cleaned contacts with rubbing alcohol....Problem Solved!!!!
Pros: Love how big it is compared to most mice. It fits super comfortable and you dont have to drag your pinky on the ground. Cord is cool and braided. The laser is super accurate and quick. The option of the movable buttons is very nice as well
Cons: Braided cord is way too stiff. Which I believe is causing my cord to have poor connection and stop working sometimes. Had the button start double clicking at holding when i was only clicking once. Took the mouse apart and cleaned contacts with rubbing alcohol....Problem Solved!!!!
Summary: Pros: Feels good in hand Works flawlessly, precise, etc. Cons: Left click failed after two years of gaming use. I have to say, as neat as adjustable thumb buttons are in theory, they just don't feel good. They lower the build quality of the mouse, making it feel less solid. Minor nitpick, but IMO I'd prefer to just get used to a static placement. Overall, a great mouse. Disappointed it didn't last longer.
despite me using a nice mouse pad (by the same brand

Summary: This mouse has been odd. When it works, it works amazingly. It's very smooth and has pinpoint accuracy. However, despite me using a nice mouse pad (by the same brand, Razer) it has some serious problems getting hung up sometimes. While this only happens once or twice a day, if that, I don't really find that acceptable at all of a gaming mouse.
Summary: I really want the mice to be good. They look great, feel good in the hand, and perform solidly in games, but unfortunately they are just cheaply made. They do not stand up to regular usage and customer support has taken over a week to finally contact me and suggested I try a different computer....Seriously so disappointing.
Pros: Smooth feel, Sleek Finish, great in game accuracy......when it works.
Cons: I have owned 3 of these mice, and they all have failed, 2 for the same reason. The first one I owned the buttons stopped responding. The second 2 have had the cable go out . I opened the second one up, re-soldered the cable and then it worked again for about a month. Now, after a little over a year of owning this mouse the cable has gone out as well. Contacted support on this one, over a week later get a reply telling me to try a different PC....Like I did not try tha...
