We've converted this review to Test Bench 1.5. This update adds a new Main Button test group, which provides button actuation data and switch information. We've also made minor changes to how we calculate the Office usage score. For more details, you can see our full changelog here. By weighing so little, the Viper Mini’s ability to glide is unparalleled, and comes with the inclusion of Razer’s Speedflex cable, which is specifically designed to minimise drag for a more rewarding gaming experience. Performance

What’s more, the Viper Mini comes with Razer’s optical switches, meaning you’re not compromised on performance. Optical switches use light, as opposed to traditional mechanisms, giving you a generally faster performance and a bigger competitive advantage. Despite having only two lighting zones (the logo and small strip on the mouse’s underside), the Viper Mini certainly doesn’t disappoint in the lighting department, featuring Razer’s excellent Chroma RGB. Whilst we will do everything we can to meet the delivery times above, there may be factors outside of our control and we cannot guarantee delivery within this time frame.We've added a link to the newly-reviewed Fantech Aria XD7 in the Wireless Versatility section of this review. We've added a link to the newly-reviewed Razer Cobra Pro in the Wireless Versatility section of this review. We've added a link to the newly-reviewed Razer Viper V3 HyperSpeed in the Hand Size Recommendation section of this review. Despite its smaller size, the Viper Mini still looks great. It’s still got the signature aggressive lines that all of Razer’s mice have, along with the Viper name. Moreover, the typical hard plastics the Viper Mini is made of make it comfortable and sturdy, even with that unexpectedly lower weight.

While it’s not specifically aimed at office use – marketed much more towards the gaming side of things – the Viper Mini is also well-placed during long office hours, with its compact size making it a decent little travel mouse. The Viper Mini comes alive with Razer’s Synapse 3. Despite a lengthy install process, the six programmable buttons can be tinkered with untill your heart’s content, from opening system programs to programming macros. What’s more, with Hypershift enabled, the button tally of the Viper Mini is practically doubled to 12, giving you even more options for programming. We've added a link to the newly-reviewed Razer Cobra in the Sensor Specification section of this review. The Chroma system also allows for connection to other devices such as the Philips Hue home lights, letting you build your RGB kingdom beyond your office or bedroom. The ability to tie the lighting with a whole host of other devices is a really cool idea and implemented very well. Should you buy it? That said, the Viper Mini might just be a little too small for some people’s hands, and its two lighting zones may not be enough for those who like a flashy light show.

You can get cheaper gaming mice such as the Logitech G203 and Corsair Harpoon, but these options aren’t quite as light and don’t offer the same level of sensitivity. Plus, you get all the flashy RGB and customisation features with Razer’s software which is so far unrivalled. From the outset, the Viper Mini does what it says on the tin. While it’s marginally taller than the standard Viper at 38.3mm, it’s also 4mm narrower, bringing the weight down to a dainty 61g. The Viper Mini also appears to be one of the first Razer mice to use a 8500 DPI sensor, which makes a change from the zany 20,000 DPI sensors featured on the likes of the Basilisk Ultimate or DeathAdder V2. With the sheer lightness of the Viper Mini in mind, 8500 DPI is absolutely plenty – it’s already sensitive enough and works perfectly.

This update modifies our Hand Size Recommendation test, adding a more granular hand size recommendation chart. We've moved several minor tests into different test groups, removed the Travel usage, and added a new Raw Performance usage. For more details, you can see our full changelog here. Despite its size, the Viper Mini offers a fantastic gaming experience. With its 61g weight and wired connection, it offers something light with no latency whatsoever. Some of the best things in life are mini: the Mini Cooper, Cadbury’s Mini Eggs and Dr Evil’s Mini-Me just to name a few. Gaming-peripheral brand Razer has clearly caught on after launching the Viper Mini.
