Closer Examination

Looking at the left side of the mouse, we see two side buttons; these are placed perfectly for smaller hands like mine, but may not be as comfortable to use for larger hands. They have a nice satisfying click without being too hard to push and feel very sturdy, unlike a lot of lower-priced mice. The Harpoon also has a textured rubber grip for some extra comfort and to stop your hand from slipping.


The right side of the Harpoon RGB is contoured with the same rubber grip as on the left, and the bottom of the mouse flairs out slightly, acting as a rest for your fingers, which, while great for claw or fingertip grips, does make a palm grip a little bit more uncomfortable until you get used to it and modify how you hold it.


The rear of the mouse has a nice curve to it, allowing for a good grip that is neither too high or too low. The Corsair logo has an RGB LED behind it that can be made to match the lighting of the rest of your system.


The LMB and RMB buttons have a very nice smooth design with a nice "click" to them due to their Omron switches - they have a satisfying feel and are responsive. The scroll wheel feels a little stiffer than with the last few mice I have reviewed, but isn't too stiff, allowing for perfectly fine scrolling. I find a stiffer mouse wheel to be better for gaming since it allows you to switch weapons easier, but it does mean it struggles a little bit more in an office environment. Directly behind the scroll wheel is another button; by default, this button cycles through five DPI settings – 500, 1000, 2000, 4000, and 6000 DPI – but the value can be configured via the CUE software interface, in increments of 250 DPI. You can also set a different LED color to each step to know which DPI you are using with just a glance.


I have already mentioned the contours the Corsair Harpoon RGB boasts, but these two pictures really show off what I mean. You can see that for a mouse that is aimed toward a budget market, there is a lot of design work done; it isn't just of a standard shape with no personality.


The cable for the Corsair Harpoon RGB is 1.8 meters long and unbraided; it does take a while to straighten out so it doesn't keep getting in the way of the mouse, but a mouse bungee solved that issue for me quickly. The USB connector is the same as on most other Corsair products, with a very good rubber protector around it. The cable attaches to the mouse on the left-hand side, off center. I have seen some people who were confused by this, but have never had a problem with it myself. The only difference is that I have to give it a little extra cable when using it with a mouse bungee.


The underside of the Corsair Harpoon RGB has four large PTFE skates, which allows for a nice glide across multiple surfaces. The sensor is a Pixart PMW3320 Optical sensor, which was released late last year and is a good option for a mouse at this price point; a lot of other mice that use the same sensor are far more expensive, such as the QPAD DX-20.
