Talking about Razer Viper Ultimate is not easy: like all Razer mice it is an absolutely over the top product, whose build quality and integrated technology set school in almost all respects.
But it is also a product that not only integrates technologies at times futuristic up to now, but does so in such a transparent and obvious way that one almost wonders how we have done so far.
And it's difficult because inevitably the Razer Viper Ultimate is likely to be called in the next few years as the forerunner for a new generation of mice, and this piece accordingly cited in many other reviews – we hope to do a good job and tell you about it in the way. More appropriate. In the meantime, sit comfortably because there is so much to say.
Razer Viper Ultimate, the review
Out of the box
The box of the Razer Viper Ultimate opens leaving the first novelty to those who already know the brand: the welcome sheet no longer mentions the mantra “Congratulation, there is no turning back” (as in the case of other mice we have tried such as the Razer Mamba) but now offers a more aggressive “Unleash your true potential”.
Just below it immediately shows itself in its refined black satin plastic armor, with the exception of the shiny plastic finishes and the viscose rubber sides.
Below, the Razer Viper Ultimate shows the white rubber pads instead of black like on all other Razer mice and the power buttons and the one for the quick change of the game set.

In the same box there is the USB-A / MicroUSB cable with soft fabric cover and just below the Razer Mouse Dock, the support base for charging with a double function, one of the many new features as we will see shortly.
The whole is completed by the USB-A wireless antenna, which the Viper houses in the special drawer just under the body.
The first thing you notice when putting the mouse on the road is the weight: very light, just 74 grams, which when tested on a modern mat (like this one for example) literally makes the Viper whiz where many other mice, even in the sector, require more effort.
A thread that is not there
Aesthetically, the new Razer Viper Ultimate does not differ from the previous model, which for the moment remains on sale at a lower price, but in reality the product is radically different.
If the keys have the same optical technology for the click, able to significantly increase precision while reducing noise, the new model loses the need to use the cable, since it can now work even without thanks to the new Razer HyperSpeed technology, a innovative wireless transmission system that guarantees up to 25% faster speed than the rest of the market.

This transmission system, together with AFT, the technology that dynamically scans and changes the frequency band according to the availability of the various channels (already seen on the Razer Lancehead and Razer Lancehead Wireless) allows the Razer Viper Ultimate to use an extremely wireless connection. capable, interference-proof and above all with incredible stability during movement.
What do these innovations mean on the practical side? Above all precision, in addition to speed and naturalization of the tracking, an extreme feeling of safety during use, especially when you remember that there is no wire.
We emphasize that the Razer Viper Ultimate offers a pooling rate of 1000 Hz wirelessly, a very high figure when compared to most models (whose wireless values do not exceed 100 Hz).
The other part of the desk
Inside the package we also found the Dock, an accessory not essential for the correct functioning of the mouse, but really intriguing and comfortable.
For correct operation, the USB antenna must be connected to the computer (Mac or PC, we will see the differences later) and the mouse switched on via the button at the bottom.
However, the dock basically acts as a USB HUB by hosting the antenna and recharging the mouse when it is discharged or both: in the latter case, the Dock changes its lighting to Red when the charge of the internal battery becomes critical.
In reality in Razer's ideas the Dock is connected to the computer and houses the wireless antenna, but in our view the Dock is also well connected via USB to an external power supply, so as to charge the mouse at night when the computer is off. : in this way, however, the lighting is lost.
20,000 dpi under the sea
But if you think the new features of the Razer Viper Ultimate stop at the wireless chip and dock you are wrong, because we are just getting started.
On board there is a new sensor, the Razer Focus + optical, capable of reaching up to 20,000 dpi resolution, 650 IPS (inch per second) and 99.6% accuracy, the highest expression in the market today, as well as all the mice now on the market also in the Razer price list.
The new optical sensor is equipped with technologies such as Smart Tracking, capable of automatically mapping the various surfaces where the mouse moves without user intervention, the asymmetrical Cut-off, which independently favors the way in which the mouse moves. we raise or lower the mouse during the game to move the cursor range and Motion Sync, which in itself is not a new technology but a significant improvement in the tracking system when using the mouse.
All these systems, completely transparent to the user, make the experience of the Razer Viper Ultimate very natural, almost intimate we would say, as the natural extension of the hand must be.

Synapse
The operation of the mouse is designed to pass through Synapse 3, Razer's software for total and complete control of all its functions.
The software interface is very nice and in full line with the design of the Razer Viper Ultimate mouse: all the parameters can be set in a PC and recorded in the memory of the mouse to be then recovered in a second PC if necessary. (very important factor for those who play eSports tournaments on preconfigured PCs).
Synapse also manages the operation of the Dock, in particular in its brightness and effects, if and only if it is connected to the PC via USB.
Unfortunately, on Mac Synapse 3 is still latent, even if the writer does not lose hope of seeing it again: nevertheless the mouse works very well (both flush and wireless) with the only limitation of not being able to change the operation of the keys.

Considerations
Razer Viper Ultimate is an excellent mouse: very light, aggressive, with a curious feature of having the best technology in the world on board but offering a completely transparent guide to the user, who only has to worry about configuring it for the first time. and to play.
One of the fundamental factors of this version is the wireless operation, in our tests flawless, with a battery whose duration can reach 70 hours (with lights off), therefore a week of intense use, but which in our texts with lights on ( and with pride) has exceeded two days with a charge well over 50% (remember that with these characteristics and with this type of chip the consumption is monstrously higher than traditional mice).
Considering all the premises and what we have seen, we are convinced that this mouse is not a point of arrival for Razer but a starting point and we still expect many models with these characteristics in the future, excellent for those who play, excellent for those who work with precision.
Pro:
• Lightweight • Wireless operation • Dock is interesting • Some technologies on board are very interesting
Cons:
• Mac drivers are missing • Battery usage is affected by different active capacities
Price:
• 169.99 Euro
Razer Viper Ultimate is available in the official Razer store but readers can also order it from the Amazon.co.uk pages. For the moment, the Razer Viper flush model remains on the list, which we have talked about in detail here.
