This mouse is one of the less expensive wireless mice from Logitech, and it gets the job done. It's comfortable to hold; it performs well across many different genres; and its low-power and Bluetooth options give it some productivity viability as well. If you have enough money to splurge for the versatile G903 or the more refined G703 instead, you probably should; otherwise, the G603 is a fine choice for the competent, everyday gamer who doesn't need anything too fancy.
The G603 is a fairly small (around 4.9 x 2.7 inches) mouse that looks like it'd be equally at home with a desktop or a laptop setup. Although the mouse has neither a thumb rest nor textured sides, it does have an ergonomic design, with a gentle curve on the right side and a steeper curve on the left. The central gray panel on the mouse lifts up to reveal storage space for a wireless dongle, as well as two AA batteries. Unlike some of Logitech's other wireless mice, the G603 can't be used with a USB cable, so whatever you do, don't lose that tiny, tiny dongle!
The mouse has six programmable buttons: a left button, a right button, a clickable scroll wheel, a dots-per-inch (DPI) sensitivity adjuster just beneath that, and two thumb buttons. Everything is pretty much where it's supposed to be. There are also two buttons on the bottom of the mouse. One changes from the default power consumption to a low-power mode for productivity. The other shifts between dongle and Bluetooth connectivity.
So in short...
GOOD:
- Comfortable design
- Fair price
- Great wireless performance
- Fully programmable buttons using the Logitech software
- Bluetooth connectivity as well as regular wireless (with USB dongle)
- Use two AA batteries and not on board rechargeable battery
- USB dongle extension cable included
- Long battery life
NOT SO GOOD
- Use two AA batteries and not on board rechargeable battery (for those who prefer to have a rechargeable battery instead)
- Cannot be used connected to USB cable

Great Mouse - Battery Life Not So Good
I love this mouse. It has a great feel and great responsiveness, but don't expect battery life of anywhere close to what they advertise.I started with the G603 set to "LO" battery usage after I purchased it on 06/15/2020. I am not a gamer, so I did not need to run it on "HI". I powered it with 2 brand new Duracell alkaline batteries. The mouse became sluggish, so I replaced the Duracell batteries on 02/05/2021 with 2 Ray-O-Vac alkaline batteries. So, I got 235 days of battery life out of the first set of Duracell alkaline batteries. This is about 7.7 months, not the 18 months that was advertised! In May of 2021 I started having problems (about 3 months of usage with the Ray-O-Vac batteries). I was getting double-clicks for a number of my single-clicks. I did not recognize the behavior until it got a bit worse toward the end of June 2021. I contacted Logitech Tech Support on 07/12/2021 and told them what the problem was. They gave me a long list of troubleshooting steps. None of which solved the problem. I thought the problem may have subsided, but it had not. It continued to get worse. I contacted Logitech Tech Support again on August 19th of 2021. They gave me another long list of troubleshooting steps. Again, none of which solved the problem. Finally, on 08/28/2021, while watching a movie I was reminded that as batteries age and are used up that their working voltage declines. I know that things can get flaky with a lot of devices with lower than required voltage. With that in mind I decided to test the batteries in my G603. The batteries tested good, however only marginally so. So, I got two new AA alkaline batteries and tested them. They tested good with a much higher reading on the battery tester. I put the new batteries in my G603. THE MULTIPLE-CLICK ISSUE ON A SINGLE-CLICK DISAPPEARED IMMEDIATELY!Conclusion, the first thing on Logitech's troubleshooting checklist should have been to:"REPLACE THE BATTERIES WITH FRESH ONES BEFORE YOU RECOMMEND DOING ANY OTHER FORM OF TROUBLESHOOTING!"This would have saved a lot of wasted time for both Logitech Tech Support and especially for me!So, remember, if something starts to act flaky, you may want to replace the batteries first before moving into that long list of Logitech troubleshooting steps.After all of the hassle with this issue, my new battery protocol for my G603 is to use rechargeable batteries and replace them every 3 months with freshly charged ones.

The G603 is a fairly small (around 4.9 x 2.7 inches) mouse that looks like it'd be equally at home with a desktop or a laptop setup. Although the mouse has neither a thumb rest nor textured sides, it does have an ergonomic design, with a gentle curve on the right side and a steeper curve on the left. The central gray panel on the mouse lifts up to reveal storage space for a wireless dongle, as well as two AA batteries. Unlike some of Logitech's other wireless mice, the G603 can't be used with a USB cable, so whatever you do, don't lose that tiny, tiny dongle!
The mouse has six programmable buttons: a left button, a right button, a clickable scroll wheel, a dots-per-inch (DPI) sensitivity adjuster just beneath that, and two thumb buttons. Everything is pretty much where it's supposed to be. There are also two buttons on the bottom of the mouse. One changes from the default power consumption to a low-power mode for productivity.

It's the perfect "I want all the hi-tech mouse stuff, but I don't want to spend insane amounts of money" mouse for PC gamers.

The light on top is a nice RGB led, used for indicating DPI level, battery life, and performance/endurance mode. You can choose to install one or two AA batteries, since they're wired in parallel, adding two gives you longer battery life but heavy weight. It comes with Duracell OEM batteries (nice touch, Logitech, only company I've ever seen to not include crappy chinese weird batteries), I've been running on just one in performance mode since I got my mouse and it's still in the green battery life.
The entire grey section of the mouse is one piece that comes off, held on only by 3 neodymium magnets. That includes the mouse buttons themselves, they come off when you change the battery, which is weird, but it works fine, buttons always end up in the exact same position every time.
There's a switch on the button for off/endurance/performance (performance being the low latency mode, endurance being more like a regular wireless mouse), and another RGB LED indicating wifi/bluetooth mode, easily selectable with a bluetooth/wifi toggle button. At first the button didn't do anything for me unless I unplugged the RF receiver from the PC, I contacted Logitech support, they just told me to uninstall/reinstall Logitech Gaming Software, and sure enough that fixed it. Now I can instantly jump between using the mouse on my PC, and using it on my Android phone just by pressing the button on the bottom of my mouse.
I personally can't really tell the difference in latency on 60hz monitors, maybe on a 144hz monitor you could notice. But I run in performance mode anyway. I've seen the Linus video at the logitech labs, they have the proof that it is faster than even wired mice.
For some reason their manual recommends a distance between the mouse and the USB receiver as small as 20cm. That's tiny. I'm at about 150cm without issue, I'm not sure if they're suggesting for interference or latency.
The plastic is super smooth and silky, very nice, nothing feels cheap at all. The weight with one battery is perfect for me. The sensor is excellent. And where this mouse really shines is the plethora of customization options in the logitech software for nerds like me. It's the perfect "I want all the advanced mouse stuff, but I don't want to spend a ridiculous amount of money" mouse for any PC gamer.

Then I noticed that the cover where you put the batteries in came off very easily, like way too easily.
As you can see in this image the previous owner broke the clip that holds the mouse cover on and then returned it.
I also noticed that the bottom of the mouse has little scuffs and scratches on it. Confirming that it had been used.
Luckily it has weak magnets to hold it in place or it would not be useable.
Very disappointed to get a used and broken mouse from Amazon. Unfortunately I'm not in a position to be able to return it.
Otherwise if functions great.
