Works flawlessly for drafting use...
Color: Black, Style: Wireless, Pattern Name: Mouse
This mouse has been a great upgrade for my setup. The wireless connection is fast and reliable, and I honestly can’t tell the difference from a wired mouse. The sensor is very responsive, and everything feels smooth and precise, especially combined with the Logitech G mouse pad.
I actually use this all day at work for drafting, so precision and comfort really matter, and this mouse delivers on both. I’ve even purchased several more for my drafting team, and everyone has been really happy with it.
I also like the customizable weight system—you can adjust it to feel just right in your hand. Overall it feels solid, well made, and comfortable for long hours of use.

This is the last mouse you will ever buy
Color: Black, Style: Wireless, Pattern Name: Mouse
Just buy it.
What can be said about this mouse that hasn't been said before? This is the perfect mouse, there is no contest. I know it is a bit on the pricier side, but if you need a mouse, just get the cheapest one you can get and start saving to get this one, IT'S THAT GOOD.
The mouse glides over any decent mouse pad, you don't need to get a Logitech one. The shape is perfect for all kinds of grips and the weight system is great for customization.
The led has different brightness levels, including turning it off completely to save more battery, and the keys are just silent and satisfying to press.
Again, this is the best mouse ever, no other mouse will offer a better value for your money than this one. A bit steep, yes, but worth it.

One of the best mice I've ever owned
Color: Black, Style: Wireless, Pattern Name: Mouse
I was a little skeptical about this mouse but after 3 weeks of use it's continued to be my favorite mouse. Not only does it. Have a good feel. It is very durable and customizing. The weight is fantastic. If you get the charging pad it just glides. But is definitely worth its money

Impressive and Comfortable
Color: Black, Style: Wireless, Pattern Name: Mouse
Only after a couple play sessions in BF6 with this mouse, I can already feel how much more precise I can be with it. My first play session was a bit rough getting used to the feel of it. It’s quickly getting more natural. I switched from a ghost keyboards m1 mouse to this.
The left and right mouse clicks feel a bit more stiff than my m1 mouse which I like. Easier to avoid accidental inputs. All the other buttons feel solid with clean clicks.
The mouse wheel is a very different feel with more significant bumps while scrolling, but it adds a more tactile feel being easier to control. It also has a release that lets it just spin for probably more work type use rather than gaming.
It’s easy to setup, basically plug and play but a bit confusing. It comes with of course, a charging cable but the Bluetooth usb comes in some sort of housing that plugs in by the charging cable. Not sure if that is better or worse than how I have it now which is the usb receiver plugged into the back of my pc. Works fine.
Looking at the Logitech website shows up to 48 hours of battery life with default lighting, or up to 60 hours with no lighting. Fully charged it showed 26 hours (25 hours now at 96%). And turning off the lighting at 96% only goes up to 28 hours. Which is plenty as I usually plug my wireless device in to charge after use.
My favorite part of this mouse is how comfortable it is. It’s a bit thicker filling in my smaller hands more compared to my m1 mouse. Another nice added comfort feature is the thumb ledge. It keeps my thumb off my mouse pad, and helps with control of the mouse in high stress fps situations. The weight also help in precise aiming. My m1 mouse was 65g , the g502 is 111g plus the 1 big weight and 2 smaller weights I added making it go up to maybe 119g.
Highly recommend this mouse, and will try to update if it fails prematurely.

It's just a Proteus Core, but wireless. Wait... it's a PROTEUS CORE, but WIRELESS!!!
Color: Black, Style: Wireless, Pattern Name: Mouse
I've been using a Logitech G502 Proteus Core for a couple of years, and I've been wanting a wireless mouse for ages however, I had been hesitant to switch to anything else because I loved that G502 Proteus Core.
Then, this mouse came out. I knew it was time to upgrade. I get a mouse that looks, feels and performs identically to my Proteus Core. No, scratch that, BETTER than my Proteus Core. Except now no more wire wrangling. No more wire catching on the edge of a table or needing to tape it down. Except the sensor is faster and better than my G502PC, and the wireless mouse is somehow LIGHTER than the wired version. What kind of space age magic is this!?
When I got it at first, I was actually a little disappointed. I had been excited for this new, fancy mouse that was going to step my game up. But then I got it and it just felt exactly like my old one. It felt like nothing has changed. The wait to use it came to a somewhat anticlimactic end.
But then I thought about it and realized..... IT FEELS EXACTLY LIKE MY OLD ONE. I got literally exactly what I loved before, but this time with RGB lighting and no cord! What had I expected? I got literally exactly what I wanted, and it felt like home.
And the battery life, of my goodness, the battery life. I've been using this mouse since mid Early/mid-May. I probably use my mouse for about 1 to 4 hours a day, sometimes every other day depending on schedule. I charged this mouse to 100% on my first day of ownership. I haven't charged it since, and my battery currently reads 64%. Incredible. Over a month of regular and consistent use, with lighting on (at about 60-75% brightness, purple) and I haven't even gotten it to half charge. That tells me I've probably got another month or so of battery life to go!
I have been BEYOND satisfied with this mouse. I only had one minor hiccup. Initially I put the wireless receiver in the rear of the tower, straight into the motherboard's primary USB 3 port. Unfortunately, I noticed that I would get occasional stuttering and hitching with the mouse cursor. After a bit I noticed that it only happened when my cell phone was on my computer desk in front of my mousepad. I relocated the receiver to the USB3 slot on my Corsair K60 keyboard, problem solved. I haven't had one stutter or hitch since. I think my cell phone's WiFi signal was causing some form of interference. I could reproduce the problem with my cell phone location every time, so I'm confident in what the issue was.
BEYOND satisfied with this product. If you have ever used any of the Logitech G502 line - or mice of a similar shape - this product is an absolute NO BRAINER purchase.
