Razer Viper Ultimate Review

Razer Viper Ultimate Review

Razer Viper Ultimate 02The Razer Viper Ultimate has a lot to live up to – there aren’t many gaming brands that are as big as Razer, and this mouse is allegedly the best rodent that the green team has ever produced. And, with US and UK prices of $150 and £150 placing this mouse at the top of the market, it’s got a lot of work to do to justify the cost.

The Razer Viper Ultimate is wireless, packed with tech and it’s expensive – but is it actually any good? Our Razer Viper Ultimate review will find out.

Design and Features

The Razer Viper Ultimate certainly lives up to its name when it comes to its specification. Its sensitivity level of 20,000 DPI is one of the highest levels ever included in a mouse. It’s 2,000 DPI higher than our current favourite, the Corsair M65 RGB Elite – a wired mouse that costs $60 and £60.

The huge DPI level is joined by a tracking speed of 650 IPS – another high-end figure that compares well to the Corsair, which topped out at 400 IPS. And, finally, the Razer has polling rates that peaks at 1,000Hz, which is a conventional number.

It’s marking-leading sensitivity and tracking, and it’s no surprise that the Razer has this sort of hardware inside. The Viper Ultimate is supposed to be a top-tier product, after all, and it’s also designed for esports, first-person shooters and other competitive scenarios – areas where rapid response and accuracy are vital.

They’re high numbers, for sure, but it’s important to not get caught up here. A 20,000 DPI sensitivity level sounds great, but virtually no gamers or pro players will actually use it. It’s simply far too sensitive to be of any practical use.

If you’ve got a gaming mouse over around 15,000 DPI then you’re going to be absolutely fine – no matter if you’re an FPS enthusiast, a Fortnite fan or an esports professional. The Corsair and Razer are both easily good enough, and higher numbers are just an arms race these days.

The 650 IPS figure is more important, because it means that the Razer will deliver incredible accuracy when it comes to its optical sensor.

The Razer Viper Ultimate uses the Razer Focus+ optical sensor, which is also used in the right-handed, button-filled Razer Basilisk Ultimate.

The Viper certainly looks like a more focused product. It’s smart and sleek, with a smooth coating on the top and welcome, grippier textures down both sides. The only RGB LED on the mouse is the Razer logo at the rear, and build quality is great – just as good as the Corsair.

The Razer is ambidextrous, which means it has pairs of customisable buttons on the left- and right-hand sides. Elsewhere, the Viper Ultimate has the usual two main buttons and a scroll-wheel. There’s a DPI adjustment button that supports five different customisable sensitivity levels, although it’s on the bottom – so it’s a little tricky to reach.

The bottom of the mouse also has a small cavity that can house the 2.4GHz wireless dongle when travelling.

The cheaper Corsair mouse looks more outrageous, with exposed metal. It also has more buttons – including a sniper button and DPI adjustment buttons on top. However, the Corsair mouse isn’t ambidextrous, and it’s not wireless either.

The Razer Viper Ultimate weighs 74g, which makes it lighter than the Corsair – that product had adjustable weights and ranged between 97g and 115g. The Viper is 38mm tall and 66mm wide, too. That means it’s also physically smaller than its key rival – the Corsair was 39mm tall and 77mm wide.

While the Razer’s dimensions and weight will not be a problem for the vast majority of players, those who prefer a heavier peripheral may want to look elsewhere – especially as the Viper has no adjustable weights. Similarly, people with larger hands may want a physically bigger mouse than the Razer. Gamers who prefer to use a palm grip could struggle with the lack of a larger bulge at the rear of the Viper.

Razer Synapse is a great app: straightforward and sensibly-organised, with loads of settings. An unlimited number of gaming profiles can be stored here alongside the five saved on the mouse itself. There’s a neat toggle for switching between left- and right-handed modes.

The final piece of the Razer’s puzzle is the charging dock. This small, USB-powered accessory is smart. Magnetic pins to hold the mouse in place. An RGB LED around the bottom that changes colour depending on charge levels.

It’s a neat addition that makes your mouse look even cooler. We had no battery life issues with the Razer Viper Ultimate – it easily made it through sixty hours of gaming.

The Razer Viper Ultimate uses optical switches on its two main buttons – not conventional mechanical switches.

Razer says that the deployment of optical hardware makes the main mouse buttons faster, less prone to errors and more robust.

We certainly had no issues when it came to main button performance during gaming: the buttons are fast, responsive and consistent, with no obvious mistakes or missed presses. The buttons are also rated for 70 million clicks, which is a superb endurance level – 20 million more than the Corsair.

The Razer is great when it comes to wireless performance, too. The latency level of less than 0.2ms matches any wired rodent, and the Razer was flawless during our tests. The Viper Ultimate was accurate when used on several different surfaces, with no sign of smoothing, artificial acceleration or angle-snapping. It’s certainly got the speed and accuracy for esports and twitchy, fast games.

When it comes to performance, though, the Razer Viper Ultimate does still have a couple of tiny issues. The Razer’s scroll wheel is a little low and stiff when compared to the taller, smoother unit on the Corsair. The Razer’s side buttons are also a little flimsy.

Razer Viper Ultimate Review – Conclusion

Our Razer Viper Ultimate review reveals that there’s a lot to like about this mouse. Its core gaming performance is great. The main buttons are fast and responsive and the whole mouse is accurate and precise.

Razer Viper Ultimate 01Whether you’re playing fps games, esports titles or anything else, you won’t have any problems, especially with so much sensitivity and DPI adjustment available. It’s not an exaggeration to say that, when it comes to core performance, the Razer is one of the best options on the market.

Elsewhere, the Ultimate has flawless wireless performance, a neat charging dock, sleek physical design and great software.

However, the Razer does have some foibles that could mean that the Viper isn’t necessarily the most suitable option. It’s slim and light, with no adjustable weights, and it has fewer buttons than rivals. If you want something with more buttons and more substance, the Corsair M65 RGB Elite remains a better option.

And, while the Razer Viper Ultimate impresses on paper with its sensitivity level, don’t be fooled. No-one needs a 20,000 DPI mouse, and no buying decision should be based on that number.

And then there’s the price, too. The Razer Viper Ultimate is fantastic, but its $150 and £150 price make it far more expensive than the Corsair – and almost anything else in the market right now.

If you do want an accurate, sensitive wireless mouse with stylish charging and flawless performance then, sure, the Razer Viper Ultimate is a worthwhile investment. However, rivals like the Corsair offer fantastic core performance for a lot less if you’re willing to forego wireless functionality and that 20,000 DPI sensor.

The mouse in our Razer Viper Ultimate review costs $150 in the US and £150 in the UK. Discuss our Razer Viper Ultimate review on our Facebook and Twitter pages.
