We’re nearing the end of our current hardware roundup. We’re on the hunt for the best lightweight gaming mouse.

This week we will be taking a look at the more premium and big brother of the Logitech G203. That’s right it’s the Logitech G403 gaming mouse, and it comes in at only 87.3g.

Looks and feel

The very first thing I notice about this mouse is its slick black design. The mouse is basically all black, except for the 2 backlit areas and some text on the bottom side.

It comes with a nice braided cable. Something that I expect at this price point. It also has one of those velcro cable ties on it, making it much easier to take on the go.

The G403 has a high arching backside to it. Like, really high. By far the tallest mouse I’ve ever used. It sits up more into the palm of your hand while allowing your hand to sort of drape over it. It doesn’t really fill out your palm that well. It’s a little awkward at first, but with time I’ve grown to like it. The design does a good job of keeping your palm off of your mouse pad.

Both sides have a nice, flat black rubber grip. It’s one of my most favorite things about this mouse. I would say this is a high grip mouse.

This mouse features a right side sloped design. Meaning from the front it slopes down toward your pinky, leaving your hand in a more open position. There is plenty of room on the right side to put your pinky too.

The scroll wheel oddly sits higher than pretty much any mouse I’ve ever used. It’s one of those double-edged sword type of things. It’s really nice if you have to do a lot of scrolling, but overly annoying if you don’t. It does take noticeably more effort to scroll due to how much higher you must arch your finger. The wheel scrolls nicely and has a nice grip. Unlike the Logitech G203, the scroll is much smoother, and the scroll wheel has a nice softer shape to it.

The forward/back buttons are nice and big. They aren’t necessarily hard to hit, but I do wish that they would make them come out just a little bit more. I find hitting the back button I really have to flair out my thumb a bit more than I’d like. This does sort of change with how I grip this mouse.

There are 2 backlighting zones on this mouse. 1 on the backside logo area, and the other through the middle of the scroll wheel. A little disappointing considering the Logitech G203 has more lighting with a swoosh on the backside. You can’t set each zone independently either, except to turn the lighting totally off.

Lastly, the mouse comes with an extra 10g weight, allowing you to have a weight of 97.3g. It’s really easy to change once you figure it out. The bottom plate is just held on by magnets so all you do is push down on the depressed circle and pull it out. It’s really an ingenious design, and I love it.

Software

Being a Logitech mouse, you use the  Logitech Gaming Software (LGS) to configure it.

There isn’t all that much that is different from when we looked at the G203. So check out that review if you want the run down.

The biggest difference is this mouse has a DPI of 200–12000, and you can adjust it to increments of 50 DPI.

The lighting effects offered are off (solid color),  color cycle, and breathing effect.

Lastly, there is a special settings tab called Surface Tuning. We saw something similar with the Razer ABYSSUS V2. The number of options is small and reasonable here though:

  • Logitech Cloth Gaming Mouse Pad
  • Logitech Hard Gaming Mouse Pad
  • Factory Default

Verdict

Logitech G403 review score

The Good: Solid high back design, quite ergonomic. Nice rubber side grips. Good scroll wheel feel and use. Big back/forward buttons. Braided cable. Easy to change 10g weight. Good software.

The Bad: Annoyingly high scroll wheel. Slightly awkward back/forward buttons. Takes some getting use to.

It’s a pretty good mouse all things considered. It’s a little awkward in some places. After doing a fair bit of gaming with it over the course a couple weeks I can say that you’ll get used to it. The mouse has done well in long sessions due to its design. So yeah definitely check this one out, it’s one of the best gaming mice I’ve ever used.

I’m not sure I can crown it the king of lightweight gaming mice. There is another killer in contention which we’ll cover in our next review.
