The best mouse is the best mouse
Color: Black, Style: Wireless, Pattern Name: Mouse
I've used the wired in the past and it was my favorite mouse and after using an ASUS wireless mouse for the last 2 years I decided to go back to the Logi G502 only the wireless version this time. Connectivity is great. Disappointed that it doesn't use USB-C to charge the mouse itself, but whatever. This thing is so great and more comfortable than the last mouse I was using. That's a win
All I'm saying is it's great to have this mouse again because it's hard to argue that this is the best mouse for gaming. I can't comment on battery life as I just received it but from the rest of the reviews, its has great battery life.
But upon immediate use, I just can't recommend this mouse enough!!!

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
