It is a great mouse has weights that you can adjust and the dpi has a very wide range

This is a great mouse. But it is rather large and back centered. Really made for palm users. A claw grip is hard without large hands. The thumb glide on the side is awesome and makes it so you need very little pressure to hold the mouse.

Feels good to use, like the adjustable weights. Took so getting use to the hand position, but I like it

CORSAIR - Nightsword RGB Wired Optical Gaming Mouse with Adjustable Weights - Black is a great product. It was installed and running smoothly. I recommend this product to everyone.

Perfect for gaming. The dpi setting button could be moved as my one flaw with this mouse.

Awesome Awesome Awesome Awesome Awesome Awesome .

Two years later and it’s still working very strong love it here

I have been a fan of Corsair forever. This mouse is absolutely awesome and goes well with my Corsair gaming setup.

Love this mouse. So far I am enjoying and using the heck out of this thing. Swapping the weights and finding that sweet spot is a nice feature. Buttons seem to be holding up well through all my FPS's, No double clicking issues. Solid product for the price, especially at $60 bucks.

I like it so far, will have to wait and see if it lasts for over a year.

Bought in March and by July would rarely double click, now in September out of 100 right clicks 14 are double clicks.

Love my Corsair keyboard and thought I'd try out this large mouse because a similar Logitech was too flimsy, had out-of-date software required to program keys as I wanted. This mouse is comfortable for my larger hand, and I like the thumbpad, but NOTHING takes the place of my Razer Ouroborus. However, Software/mouse buttons are very inconsistent, often failing to trap clicks or traps them with such a delay that the click is registered elsewhere on the screen. And, this is not just a fluke, but happens again and again. Probably going to a Razer because my keypad is an Orbweaver and I don't want 3 driver sets for keyboard, keypad and mouse.

this replaced my Razer Naga Trinity that was starting to double click. I like the adjustable weight and comfortable design.

Good mouse, got this one because of the 10 programmable buttons. Only complaint is that i have big hands and the mouse has kind of a off canter stance that i wouldn't prefer if i had to buy again.

I love this mouse. Easy to use. I love the different levels that it has for ur mouse to move on the streen.

Perfect controller. Works great feels great in the hands …..love it

It has such smooth movement. And easy to use with gaming programs

The mouse works great my only complaint is when the weights are put in the sensor doesn't always read the proper weights on icue. Other than that I wish there was actually enough weights to fill all slots and more weight options.

This mouse is probably not for the inexperienced gamer but I will say with the button function assignments in the app ease the learning curve. After detailed customization it adds another level to your gaming experience!

This is my first Coarsair mouse. I've always had Razer, so I thought I would give this a try. I've only had this mouse for about a week. So far it's working just fine. Time will tell though if it's as good as my Razer.
