From bodybuilding to drifting, cutting weight is essential if you want to stay on top of your game! This includes gaming where "Game Over" is not an option unless of course, you're playing the Game Over mission in Call of Duty 4!
Both keyboard and mouse have a special place in every PC gamer's heart, particularly when playing first person shooter games. Being swift and light weight are an advantage; hence the advent of gaming mice with holes such as the HyperX Pulsefire Haste.
Unlike its predecessor - the Pulsefire Raid - which has a solid shell, HyperX's new Pulsefire Haste has honeycomb-shaped perforations punched across the top and bottom of the mouse. The hole punch design not only looks like a target with bullet holes, it is also functional, allowing the Pulsefire Haste to sport a lighter and more breathable body shell. Compared to the Pulsefire Raid, which weighs 94 grams (without the cable), the Pulsefire Haste has managed a phenomenal 34-gram weight reduction, sitting at just 60 grams (84 grams including cable), making the Pulsefire Haste one of the lightest gaming mouse you can buy in 2021.
While the Pulsefire Haste jumps on the trend of honeycomb mice, the Pulsefire Haste is not overly perforated like a lot of ultra lightweight mice on the market. The Pulsefire Haste has a good balance of holes and even weight distribution across, thanks to the non perforated sides. This makes the Pulsefire Haste not feel as empty and hollow as other gaming mice with holes, which can take some time getting used to.
Perforated holes aren't the only feature as the Pulsefire Haste also has a comfortable shape and most importantly, long and wide left and right click buttons, which are clicky and responsive. There is also two clicky left side buttons and a single button DPI changer, which is located far enough from the scroll wheel/middle mouse button to prevent accidental DPI changes.
The scroll wheel is lined with textured rubber and spins freely without clicking. There are a total of 4 default DPI presets built-in, each with its own color led to help you differentiate them. These include 400 dpi (red), 800 dpi (blue), 1600 dpi (yellow) and 3200 dpi (green)

The Pulsefire Haste has a decent length (12.4cm long) to suit small and large hands with a middle hump that slopes gradually towards the back, making it comfortable to hold in either fingertip grip, claw grip and palm grip. 
To compliment the honeycomb hole design, the Pulsefire Haste comes with removable honeycomb styled rubber grips that you can stick on to the sides and right/left click buttons. The rubber side grips can be easily peeled off and add 2 extra grams to the mouse. The Pulsefire Haste measures 7cm wide and has a 3.5cm high hump.

A 1.8 meter long cable is permanently attached to the mouse. While wired mouse aren't always desirable because it causes dragging friction, the Pulsefire Haste cable has a soft construction with a fabric outer sheath likened to a shoelace, which eliminates the annoying pulling resistance of corded mice with rubber cable.
The Pulsefire Haste mouse can be customized via HyperX's Ngenuity software, which lets you tweak the lighting (color opacity and speed), dpi (from 200 dpi to 16000 dpi) and remap buttons, all of which are programmable (including the dpi button). The Ngenuity software works well but does not support OS X and, it is not an ".exe" installer type software that you can download standalone. The Ngenuity software has been geared towards Windows 10 users. If you're a die-hard Windows 7 user, you will have to create a Windows account to download the Ngenuity software from the Windows Store.
The Pulsefire Haste uses the Pixart 3335 (PAW3335) optical sensor, which explains why it is dimly lit and not brightly lit red (like regular wired mouse) because the PAW3335 sensor is used in wireless mice for its low power consumption. In terms of performance, the PAW3335 sensor is responsive and tracks well, although it sits middle-of-the-road between PixArt's high-end 3360 and 3389 sensor in terms of tracking speed (IPS), gravitational acceleration and cpi (same as dpi). You can buy the HyperX Pulsefire Haste on amazon.
