The Razer Atheris is a very compact wireless mouse. It's one of the smallest mice we've reviewed and is a great traveling companion. You can easily toss it in a bag and use it wirelessly either via Bluetooth or with its receiver, which you can store inside the mouse. It has a wide enough CPI range for most people. It's not quite as customizable as other Razer mice, but these are usually gaming-oriented. The mouse is so small that it should practically only be used with a fingertip grip, although small hands should be able to have good control with a claw grip. People with extra-large hands should look somewhere else for a mouse, as this one is probably too small.
Good for mixed usage. This mouse is designed for travel, as it can easily be tossed in a laptop bag and used on a plane or train. It's also a good option for fingertip grip users that are looking for a small wireless mouse. It offers a few programmable buttons, which can be good for gaming, but it isn't designed for these uses.See our Mixed Usage recommendations
Good for the office. This mouse is a good option for fingertip grip users since its shape isn't really ergonomic. On the upside, it offers a few programmable buttons that can make your workflow a bit easier and fluid. It's also wireless, which doesn't clutter your desk with a cable.
Great travel mouse. The mouse is very small and works wirelessly, which is amazing for working in tight places like on a plane. However, the build quality isn't the best and the top cover might come off when inside a bag.
Okay for FPS games. The mouse has excellent performance and rather low latency for a wireless mouse. However, wired mice with even lower latency are recommended for FPS games. The mouse also isn't the most ergonomic and can practically only be used with a fingertip grip. This mouse is also quite heavy for its size.See our Video Games (FPS) recommendations
Good for MMO games. This mouse offers a few programmable buttons, but won't be as good as a dedicated MMO mouse. The mouse's ergonomics also aren't ideal for most people, as its short body and small shape practically only allow the fingertip grip.
This mouse is rather small and quite heavy, which isn't recommended for ultra-light gaming.
The Razer Atheris is a very low-profile mouse that has an ambidextrous design. It has a Razer logo on the back, but it doesn't have any RGB lighting. The mouse is very small and has rubbery sides for extra grip. The mouse is available in both black and white. Razer also made a Star Wars Stormtrooper Limited Edition of this mouse, although we don't know how long it'll be available.
The Razer Atheris is pretty heavy for its small size, and it's mainly due to the two AA batteries that are needed for the mouse to work. There are also no weight optimization options.
The Razer Atheris is a great portable mouse that's travel-friendly. This is one of the smallest mice we've tested and it's also wireless, which eliminates the clutter from a cable. It can easily be tossed in a bag, especially since you have a slot inside the mouse to store its receiver. If you'd like a travel-friendly mouse that isn't as small as the Atheris, check out the very generic Logitech M510 wireless mouse.
The build quality of the Razer Atheris is just decent. It's made out of plastic with silicone grips on the side, which feels solid enough, but slightly cheap. There's no wobble or squeaking parts on this mouse, which is good. However, the top cover is fairly loose and thin. It can slightly come off during regular use, making it sometimes frustrating to use the mouse as you need to click the cover back into place. Also, the feet are pretty standard, but the center foot around the sensor is ever so slightly thicker than the rest, making the mouse spin easily, which can result in unwanted cursor movement.
The mouse's very small size affects its ergonomics, which are just okay. This mouse has an ambidextrous design that's only suitable for a fingertip grip. It's better suited for smaller hands, too, since the mouse's body is rather short. On the upside, all buttons are easily reachable.
The Razer Atheris is too small and short to be suitable for a palm grip.
Only small hands can use the Razer Atheris with a claw grip. The mouse is very small, but curled up fingers of small hands shouldn't have any issue clicking the two main buttons.
The Razer Atheris is pretty small and designed for the fingertip grip. Only extra large hands won't be suitable for this mouse as fingers can go past the mouse's body, making it awkward to use.
The Razer Atheris has amazing wireless connectivity. It can be used via Bluetooth or its dedicated receiver. You can easily choose your connection option thanks to the switch that's under the mouse, which also doubles as a power-off switch. Unfortunately, this mouse needs two AA batteries, so you'll need to change them at one point, but Razer advertises up to 350 hours of battery life.
This mouse doesn't have any cables.
The Razer Atheris's latency is pretty decent. Using this mouse for daily tasks will be great as most people won't notice any delay, whether via Bluetooth or with the receiver. However, for competitive gaming, there are better wireless options, like the Logitech G Pro Wireless or the Razer Viper Ultimate.
This mouse has excellent performance. It has a wide enough range of CPI to suit most people, and you can customize it to your preference, although you can't be as precise as other Razer mice. Also, the polling rate is customizable from 250-500-1000, but not 125Hz.
All the buttons of the Razer Atheris are customizable, and you can even set the scroll up and down to different commands. You can also reprogram the left click, but it has to be assigned to another button first. You can also set a profile switching button, but this isn't available by default.
The Razer Atheris' mouse wheel is pretty standard. It offers good feedback from the incremented design, but isn't ideal for long scrolling like office-oriented mice.
The Razer Synapse 3 software offers good customization options to Windows users. You can modify the keybindings of each button, which is saved inside the onboard memory of the mouse, meaning you won't lose your favorite settings if you use your mouse with another computer. You can also create profiles inside the app and then assign a profile switching button for you to cycle through them.
The Razer Atheris is a versatile mouse. It's one of the smallest mice we've reviewed, which is great for travel, but its performance is also great, making it a good option if you want to play a few games with it as well. It's almost only suitable for fingertip grip, but its wireless latency is pretty decent.
The Razer Atheris and the Logitech G305 are both very good mice. They each have two additional side buttons and are fairly small and good for travel, though the Razer is a little smaller. However, the Logitech feels better built and is more suitable if you prefer to use the palm grip with your mouse. The Logitech also only uses one AA battery, while the Razer uses two. On the upside, the Razer can be used with its USB receiver, or Bluetooth as well, which is a nice addition.
The Razer Atheris is a more versatile wireless mouse than the Logitech M510, but its small size might be bothersome for some users. The Atheris is a great travel mouse that offers great performance as well. The Logitech M510's performance is quite disappointing and it isn't really made for games.
