We are on the hunt for the best lightweight gaming mice in our current review rotation.

Our last review was on the Corsair Katar, a very small and lightweight ambidextrous mouse. Corsair makes quite a few lightweight gaming mice, one of these being the Harpoon.

This mouse weighs in at only 85g, so let’s check it out.

Look and feel

When I first saw this mouse I really liked the design. It has a solid look, but I found the notch by the scroll wheel a little weird. I’m not super fond of the cord being attached on the left side of the mouse. Now, I’m not sure it changes much, it’s more psychological than anything.

It is what I call a “pinky side slope” type of design. This is where the pinky side is lower than the thumb side, and leaves your hand more tilted outward. It also has a higher backside arch than a lot of mice, and sits more into your mid palm.

Each side of the mouse contains some kind of lightly textured rubberized grip. It’s not super grippy. It has less grip than the Katar but more than a mouse without. I would categorize it as a low grip.

The Scroll wheel is to me the perfect height. It feels really solid and smooth.

The back end where the Corsair logo appears can be changed to any color you want. A nice change from the Katar, but the only area that lights up is that logo area.

As far as grips go, it shouldn’t be an issue to use any grip on this mouse. I do find the mouse a little bit on the small side. Meaning it won’t do as good of a job at filling out and supporting your hand as much as some other mice.

My biggest complaint is the back/forward buttons on the side of the mouse. They are harder to hit than most other gaming mice. They sit under a ridge formed by the left click button. It’s fine for general web browsing, but for gaming, it feels awkward. A bizarre design decision to be sure.


Being a Corsair mouse, it of course uses CUE. We detailed some issues we had with CUE in our review of the Katar, but we noticed a lot more stuff in this review as well.


CUE - Actions tab.

The actions tab is where you remap your buttons. Generally, this tab is more confusing than it should ever be.

You get this nice big graphic on the right side, but it doesn’t list the actual buttons on the graphic. To make things more confusing, there are two sets of graphics. One for the front/side, and one for the back/side.

Despite each graphic showing all available buttons, you can only click on certain ones in each image. The front/side you can click on the right click, middle click and dpi switch. The back/side you can click only on the forward/back buttons.

It’s just weird and seems it’s much better to not click on the picture at all. Rather use the box to the left of it that lists all the buttons. Other vendors software have boxes that point to each button. ┬áThat makes it much easier to figure out what you can click and remap.

Oddly you can’t remap the left mouse button at all. I like to use left mouse as right mouse in DOTA 2, but there is no way to do this that I can find. I would guess they don’t want you to be able to unmap left click because that would screw things up badly. Logitech Gaming Software solves this by including an option to swap left and right mouse buttons. Razer Synapses lets you remap it as long as something is mapped to left click. SteelSeries Engine 3 lets you remap it without issue, and will prompt you with a warning if you don’t have left click mapped.

Lighting Effects

I wasn’t exactly impressed by the lighting effects on the Katar. There were too many options for having one color. But now you can see that they all use the same template and it makes more sense with multi-color.

There are some really weird choices here still though. First off there are 2 ways to set a static color. You can use the STATIC setting, duh. But there is another setting called SOLID.

I guess the biggest difference is the SOLID setting allows you to set a couple more options.

The GRADIENT setting allows you to set a color shift. Most mice already have presets for this that rotate through all colors. CUE doesn’t though, and you have to set it all up yourself. Which is great if you want custom colors, but I wish it had a spectrum cycling setting out of the box.


CUE - DPI tab.

Like the Katar, you can set up to 5 DPI profiles, as well as an extra sniper setting.

You can only set your DPI in increments of 250. I find it annoying as I want exactly 800 DPI, not 750 DPI. You could set the Katar to whatever value you wanted. So I wonder if this is an oversight or the sensor is only able to be set in increments of 250?

Part of the Lighting Effect section is repeated here so you can change the color of the mouse based on DPI profile.

The only thing you can change here is the pointer speed. I would also expect to find polling rate as well, but you must click the cog icon at the top to change that.

It’s a relatively inexpensive mouse, with an OK form factor.

Optimal for smaller hands. Has oddly placed forward/back buttons. CUE could be better.

It’s not a bad mouse, but there are much better choices for not that much more money, so I find it hard to recommend.
