double clicks in 8 hours both buttons. claim to use omron switches all u want. if you use garbage to actuate them they are still junk both main buttons failed out of the box.

Hands down the worst mouse i have ever used and this is going back the the ball mouse era. never had anything fall apart in my hands like this. corsair RMA is bogus. they send u refurbished junk that just breaks in 5 minutes. this is after u spend 6 months trying to get an rma. tried fixing it myself as i have 11 years experience with Roto/injection molding. this plastic is just junk. its barely above mc donalds cup lids..... just thicker. cant be serviced like other mice. I rebuilt left and right click on many mice in the past its easy. CM storm Xornet i got 12 years out of. now everything i buy is junk. Deathadder v2 is also trash

It's comfortable

2nd replacement, started breaking after a few months after receiving it, it kept on double clicking which was really annoying to deal with regularly. Software can be buggy and mess with the mouse's functions.

I don't think i'll be buy another Corsair product again, they've all been underwhelming and i've been disappointed in the long run.

Everything about it is great*. It feels good in the hand. The buttons feel satisfying to click, it glides smoothly on several different surfaces, and I think it looks cool with the exposed aluminum frame. It feels just the right amount of weight.

I've had this mouse for three years and the left click button is now broken. Out of warranty. Almost to the day. I'm not sure I'll buy another one to replace mine, as even though I like the mouse otherwise, I don't think a high-end mouse should lose its left mouse button after three years. I didn't even use the mouse on a gaming machine - I did graphics work on that machine that had this mouse.

If you get this, get a 4-year warranty. The left mouse button will probably break on you. Otherwise it's one of the best mice I've used, and that therefore makes it feel like a great shame, that Corsair must know about, and apparently haven't bothered fixing. Just use a different switch, guys!!

Ergonomics Weight Adjustment Feel

Left Mouse Button broke really easy.

For it to break this easily, considering the price tag, is insulting. I'm starting to see a pattern with Corsair. Even their top of the line mechanical keyboard is garbage (Key Kaps just fall off randomly).

- Comfortable - Software is ok but not great - Lasted me years with no issues - Large DPI range - Cable is durable - Lighting is beautiful

- Software can be annoying sometimes the profiles are a bit overcomplicated for what they do. Also sometimes won't save settings. - The three weights on the bottom are prone to static so don't touch them if you are in a dry room.

This mouse served me well for many years until the middle mouse button gave out. I loved it, it was comfortable and put up with a lot. I just wish the software was a bit better but in the end its a minor problem. Would recommend

broke in 8 hours. left and right mouse button are trash.

made in chinaaaa

Feels great, nice shape, nice weight.

Left mouse click gives out very quickly

Would have been a fantastic mouse if it wasn't for the very common failure of the left mouse button. I've had this for less than 6 months.

I am not one to write reviews, but this is my first. As multiple posts on the internet, I am experiencing the left mouse button click issue/failure. First 3-4 months no issues, then I started to notice the left click issue. For the next several months, the issue kept getting worse and worse to the point it is unusable. It is very disappointing Corsair has allowed this issue to continue for this long and cause consumers so much frustration. What is the point of getting a replacement if the issue starts again with a new one?! There are videos available showing how you can take apart the mouse to temporarily fix the click issue. I have never purchased a mouse whereby you have to start repairing it after a few months of use. It is unfortunate that the left mouse click issue is happening as the design, feel, look, smoothness, DPI, etc., is the best I have ever experienced with a mouse. If you are thinking of purchasing the mouse, be warned you might come across this issue. Plugged in a 12 year old mouse, until I can purchase a new mouse, and all frustration and issues went away. Definitely will not purchase a Corsair mouse again. I just hope my other Corsair products I purchased, water cooler, keyboard, fans and RGB lighting quality is better than the mouse as it will be quite expensive to replace all my Corsair products.

Great mouse.

left click stopped working after 2.5 years of heavy clicking.

I still love it...

had this mouse for a few weeks now. I like the weight and size! best hand feel so far with any mouse.

The only thing i could say is the side button to lower the DPI in sniper mode can not be remapped.

Great mouse would definitely get this one again
