Gaming Mouse Razer Viper Ultimate – Razer’s New Wireless Technology Tested

Wireless mice seem to be becoming more and more lucrative and interesting for gaming peripherals manufacturers. Logitech has already promised with Lightspeed technology that there’s no difference between wireless and wired mice. With HyperSpeed, Razer also makes that promise and has three mice in its range. We test the Razer Viper Ultimate* for you and draw a short comparison to the Logitech G Pro Wireless.

Design

Razer doesn’t determine who can use the mouse and gives it a symmetrical design. Left- and right-handed users will be happy with the Viper Ultimate because there are thumb buttons on both sides. Beside the two mouse buttons and the scroll wheel there is no DPI switch on the upper side, we find it on the lower side. If a quick change of the DPI setting is important to you, the function can also be assigned to a thumb button.

On the underside we find a few more things besides the DPI switch. If you don’t need the mouse, there is an on/off switch. There is a small storage compartment for the USB dongle.

The weight in particular makes many gamers and wireless mice angry. The battery and the technology must weigh too much, so the mouse becomes incredibly heavy. Not with the Razer Viper Ultimate. At 75 grams, it’s even 5 grams lighter than the Logitech G Pro Wireless. It’s even a little bigger than the Logitech mouse. Nevertheless, it has a pleasant ergonomics, even if it lies a little more angular in the hand.

Ergonomics and Buttons

Despite the angular design, the Razer Viper Ultimate lies really well in the hand. The flat design makes it even better for larger hands than mice with a semicircular design. The low weight ensures that nothing is felt in the hand. Players who want to add weights to customize the mouse to their personal needs will unfortunately be disappointed.

Optical switches seem to be popular with Razer right now. The Huntsman Tournament Edition already uses opto-mechanical switches. Also with the Viper Ultimate the mouse clicks are captured by infrared light. The reaction time is reduced to 0.2 milliseconds due to the superfluous physical contact. This also improves durability, as there is hardly any wear – the result is a service life of 70 million clicks.

The grid of the mouse wheel is clearly noticeable, yet it is easy to turn. The mouse wheel can also be pressed. The thumb buttons are also convincing. They are well fitted and do not tilt. The most important thing is the pressure point, because it happens more often that the keys cannot be pressed well. This is not the case with the Viper Ultimate.

Equipment

The Viper Ultimate uses a sensor that Razer developed together with Pixart. The Focus+ sensor is supposed to resolve with real 20.000 DPI at 99,6% accuracy. For improved precision, additional functions are available. Motion Sync, for example, synchronizes the mouse signals with the polling intervals of the PC. Casual gamers probably won’t notice any difference to a cheaper mouse. But professionals who rarely see wireless mice will be pleased. More information and graphics about the Focus+ sensor from Razer can be found on the product page. In general it can be said that Razer uses a really high quality sensor in the mouse. Combined with the ergonomics, this results in first-class handling.

An efficient sensor also improves battery life. Without lighting, the battery should last about 70 hours. We certainly don’t have the 70 hours full yet, but the battery lasts about 40 hours without any problems. If you forget to charge the mouse, you can also connect it with the USB cable and continue playing. The illuminated dock is included for loading the mouse. At the beginning it’s a bit fiddly to place the mouse on the dock, after that it’s held by a magnet.

Poling rate of the Hyperspeed technology in comparison

HyperSpeed Wireless is designed to make you forget you’re playing with a wireless mouse. This is made possible by Adaptive Frequency Technology. Every millisecond is scanned for free channels and possible interference. If frequencies are used by other devices, Razer makes sure that switching is fast.  It has also been designed to improve data transfer time between the mouse and PC. According to Razer, this is the lowest click latency ever measured.

So let’s make a brief comparison with the Logitech G Pro Wireless. In fact, there’s no noticeable difference in technology. Both mice respond precisely, there are no dropouts or anything else. The only real difference is in the design.

Software

For the Viper Ultimate we have to use Razer Synapse 3. As usual with Razer, we can really configure everything. It’s possible to customize every single key, even the left and right mouse buttons. It’s possible to store other functions or macros.

Razer himself claims that they pre-configured the mouse in the best possible way. But if you want improvements or just want to fine tune the sensor, Razer Synapse can also do it for you.

The lighting can either be adjusted especially for the mouse, but the Chroma Studio can also be used to configure other Razer products, so that they all have the same effect and even synchronously. The Viper Ultimate is the only one with an illuminated logo, so there aren’t many effects.

Fulness

Razer is currently bringing many products to market that are really convincing, including the Viper Ultimate. A wireless mouse in this price range is certainly not easy to sell, because wireless mice are still a taboo topic for many gamers.

But we can say that you don’t make a mistake with the Razer Viper Ultimate. There’s no difference to a wired mouse, except, of course, that the battery will eventually run out.

The fact that both left- and right-handed users can use the mouse is of course advantageous. With 74 grams the Viper Ultimate is too light for one or the other, additional weight would also be a nice feature here, but are not a must.

Razer charges for the Viper Ultimate 169,99 €*, not little money, but it is worth it. And the wireless mouse can also be operated with a cable, should the battery fail.

Very good mouse!

Razer can convince with the Viper Ultimate. You don't notice that it's a wireless mouse.
