Fits my giant hands well, ergonomic despite not looking like it should be

Logitech software is finicky. Used to communicate with my ASUS mobo for rgb, now it does its own thing.

Excellent mouse, going on 7 years now (my G5 packed it in after 6 years). I have giant hands and it fits my hand just fine, not sure what all the hate is for. Do wish it was heavier though.

Don't know why all the bad reviews. I've had mine going on 3 plus years, hasn't skipped a beat, use it all day - every day. And I'm definitely not a small person, so there you have it.

None as I can see.

Great mouse, would definitely replace with the same when this eventually needs replacing after all these years.

This mouse is TERRIBLE! its made for super small hands.

Not worth a buy.

Logitech used to be the best brand for mice but this latest mouse was modeled for either tiny Asian hands or for kids. Couldn't believe how small the mouse was compared to the average mouse size.

I would not buy this mouse and Logitech really needs to get back to making Quality products like they use to. They sure did drop the ball on this one

Nice weight to it, sick RGB, nice DPI options

I’ve seen other folks complain about this which made me realize that I’m not crazy - the left click randomly registers as a double click. Dragging windows around can be frustrating because this mouse “drops” them all the time

Logitech, you can do better :)

This mouse is weighted.

Didn't last.

Already had the first one replaced. Now less than a month later the new one is doing the same thing. Scrolling in or out when or zooming in too much when I only moved the wheel a little bit. It could be the wheel that is faulty. I will not be buying this again.

Comfortable, buttons are endlessly remappable, RGB looks great, and to their credit, Logitech's software is decent. Never experienced any tracking issues; the sensor has been flawless since day 1.

The switches are HOT GARBAGE. Left click registers as a double click about half the time. This is the second Logitech mouse that I've personally had the left-click button fail. If it fails within warranty, Logitech MIGHT replace it. If your warranty is up, you're completely screwed - after an hour on live-chat with robots and "customer service representatives" they'll offer you absolutely nothing but their "sincere apologies".

Do yourself a favour and look elsewhere until Logitech addresses the appallingly bad switches in their mice. This has been a well-documented issue for years now, which I (wrongly) thought a company of Logitech's size must have addressed. Don't make the same mistake I did.

I have had this mouse for under a year and the left click is becoming inconsistent. Sometimes I need to click really hard and in the back of the button to get a drag to work. It also has a new functionality where it will randomly double click or better yet do some magical click that does something I never thought was possible.

Left clicker

5 Stars for customability and comfort. 2 Stars for bad durability of a gaming mouse by Logitech. I expect better.

Very comfortable Supporting app Many buttons Very responsive

None

Have had this mouse for well over a year, and not a single issue! Feel sorry for those who have, this has been my favourite mouse yet! Just wish it came in white.

Garbage, button fails first one in under two weeks, second one in a year
