The Best Lightweight Mouse - Spring 2021 Mice Reviews

The Finalmouse Ultralight 2 - Cape Town is the lightest mouse we've tested. It has a honeycomb body that feels solid and only flexes slightly. It has an ambidextrous shape with two side buttons on the left. It has a streamlined look with a cream-colored body, orange accents on the scroll wheel and cable, no visible logo, and no RGB lighting.

While most lightweight mice we've tested tend to fall between 60 and 75 grams, this one is only 49g, making it only slightly heavier than two AA batteries. On top of being incredibly lightweight, it performs very well thanks to its low click latency, consistent CPI, and smooth-gliding feet that work well on both mousepads and directly on tables. It also has an exceptional paracord-like cable that's very flexible and feels durable. The mouse is well-suited to small and medium hand sizes, but it isn't recommended for larger hands. That said, it comes with latex skin grips, which may help make it suitable for people with larger hands.

Unfortunately, it lacks companion software, only has a maximum polling rate of 500Hz, and has only four default CPI settings onboard. Finalmouse also releases its products in single drops, so at this point, you can only purchase it through third-party sellers, which tends to be very expensive. If you care about weight above all else, this is the lightest gaming mouse we've tested.

The Glorious Model O is the best lightweight mouse for gaming that we've tested. It has a honeycomb body that feels very solid and an ambidextrous shape suitable for all grip types, depending on your hand size. It has two side buttons on the left and customizable RGB along both sides, on the scroll wheel, and within the body.

It has an outstanding cable that's very lightweight and flexible, and remarkable virgin grade PTFE feet that offer very smooth gliding despite their sharp edges. It also has a low lift-off distance, a wide CPI range, a very consistent CPI, and great click latency that's adjustable along with other sensor and lighting settings using the companion software.

Unfortunately, its CPI is only customizable by increments of 100, and while it's compatible with Windows and macOS, you can't install the software on macOS. While it also has a large body unsuitable for small hands in every grip type, there's a smaller version with nearly identical performance, the Glorious Model O- that's ideal for small hands with any grip type. Overall, this is one of the best gaming mice we've tested and is a great choice for gamers who prefer lightweight mice.

The best ergonomic lightweight mouse we've tested is the Cooler Master MM720. It has an extremely light honeycomb body that feels fairly well-built and has an ergonomic right-handed shape that features a groove on the right to rest your ring finger. There are two buttons on the left side and independent RGB zones inside the body and the scroll wheel.

It's best-suited for both palm and claw grips, but if you have larger hands, you may have a hard time reaching the side buttons. It also includes adhesive strips that you can apply to the sides for added grip. It has an extremely low click latency, a wide CPI range, and a low lift-off distance that's customizable using the companion software, along with a host of sensor, lighting, and button programmability options.

Unfortunately, you can only adjust the CPI by steps of 100, and the sensor undershoots quite a bit, especially when moving your cursor quickly. Also, the build quality is only decent, and the body squeaks and feels as if it may crack if you press hard enough, though we don't expect this to be too much of an issue for everyday use. That said, it's a very comfortable lightweight gaming mouse and is one of the best ergonomic mice we've tested.

The Microsoft Arc Mouse is the best lightweight mouse for travel that we've tested. It has an unusual ambidextrous shape and a compact design that offers great portability, as you can easily collapse it to a flat form. It has a good build quality, and the mechanism that locks it into its flat or arched shape feels well-built. Visually, the design is sleek and minimal, and it won't look out of place in business settings.

While it isn't designed for a fingertip grip, it's well-suited for palm or claw grips for almost all hand sizes, though you may find it too small if you have extra-large hands. It has left and right-click buttons that you can swap depending on your dominant hand, and it supports certain gestures, including a three-finger click function and a single finger dragged up or down within the button area for scrolling. It connects with Bluetooth, so there's no need to worry about losing USB receivers, and it's powered by a pair of AAA batteries.

Unfortunately, it has plastic feet that don't glide very well on desks, and its click latency is high, though this likely won't be noticeable while performing everyday tasks. It has companion software, but there are limited customization options, and it isn't compatible with macOS. While the mouse works in macOS, some functions like the three-finger click gesture don't. Overall, this is an extremely portable option that'll easily slide into even the smallest of laptop cases.

The best budget lightweight mouse we've tested is the Razer Viper Mini. It's very similar to the original Razer Viper, sharing the same solid plastic body and ambidextrous shape in a smaller and lighter form factor. Despite being extremely lightweight, it still manages to retain the same impressive build quality as the full-sized version. It has a sleek, gamer-centric look, including an RGB logo behind the crest and an additional RGB strip at the back around the bottom.

Due to its small size, it's well-suited for a fingertip grip, regardless of hand size. Only those with small hands can use a palm grip comfortably, while a claw grip should be comfortable for both small and medium hands. The feet are rounded, virgin grade PTFE plastic, and glide very smoothly across mousepads and desks. The excellent paracord-like cable is lightweight and flexible. The mouse has a very wide CPI range, extremely low click latency, and user-friendly software that allows for plenty of customization. It's compatible with both Windows and macOS, but you can't install the software on macOS. However, you can carry over saved profiles using the onboard memory.

Unfortunately, unlike other mice in the Viper lineup, it only has two side buttons on the left. It also has a fairly high CPI variation, so the sensor tends to overshoot, especially when you're moving your mouse slowly. That said, this is one of the best gaming mice we've tested and an amazing budget pick, with performance and features that rival more premium gaming mice.
