When we first tried the Logitech G Pro Wireless, straight away it was difficult for us to see how this particular mouse could be topped. We've felt this way for over a year, during which time the Logitech G Pro Wireless and later the G502 Lightspeed have stood tall among gaming mice.
Therefore, it's quite clear that it's Logitech's throne that Razer has gone for with its Viper Ultimate. Not only did Razer hold a big event in Germany that we attended, Razer states, in several press releases, that the mouse is "built to win". One would assume that the manufacturer doesn't just mean this in the gaming sense, but also for the overall market. Viper Ultimate is built by Razer to overtake its competitors, and it has absolutely done so.
The Razer Viper Ultimate weighs in at just 74 grams, and that's achieved without using the so-called honeycomb technique, where you make the design and then proceed to cut small circles out of it to reduce the weight. It's ambidextrous and has two mouse buttons on each side of the body. There's a matte black coating on top of the mouse and, on the sides, there's a rubber coating that provides better grip. There's also an LED on the front of the mouse and beyond that, the only form of RGB lighting is the Razer logo.
The construction of the mouse feels incredibly robust, and you never feel like anything has been sacrificed in terms of the density of the chassis itself. The mouse wheel also feels sturdy and doesn't wobble when used, the buttons feel solid. In other words - the Viper Ultimate is almost half the weight of its main competitor and it also appears to be better in terms of the overall construction.
The mouse comes with a HyperSpeed dongle that is housed under a small plastic lid under the chassis. Admittedly, while it's possible to transport the dongle inside the mouse now (so no more worrying that you'll lose it in your bag), we must also say that we prefer the magnetic solution on the Logitech G Pro Wireless, rather than Razer's attempt to finesse a small piece of plastic on the Viper Ultimate. In terms of wireless performance, we've said it before and we'll say it again, the HyperSpeed wireless system does exactly what the name implies and the Viper Ultimate feels just as fast as any other wired mouse that we've tried. It's impressive stuff.
The micro-USB port is shaped, should you choose to use it wired, but charging is achieved primarily via the supplied stand. The charger is a small podium upon which the mouse stands to charge through two 5 volt connectors that are magnetically connected to the device. It's a great way to create added value because while it's certainly possible to plug in the new micro-USB cable and use the mouse tethered while charging, it feels really luxurious to keep it on the stand while doing something else or overnight, to return to a fully charged mouse. Both the cable and the stand itself use Razer's new SpeedFlex cable, which is a braided cable that's both softer and has less tendency to grind against your table.
You also won't have to charge the mouse very often either. Whereas Logitech once impressed with its 48 hours of mixed-use battery life (without RGB), the Viper Ultimate stands triumphant once again with Razer's claimed 70-hour battery life. We got around 67 hours without RGB, which is extremely impressive. The Viper Ultimate is arguably among the most energy-efficient products on the market.
The Razer Viper Ultimate uses optical switches that Razer claims are up to three times faster than mechanical ones. It's difficult to measure this, but we can confirm that the click provides a nice resistance and feels tactile. In addition, the Viper Ultimate is the first Razer product to use Razer's new Focus + sensor, which offers the industry's highest DPI sensitivity. We're talking 20,000 DPI here, and while that's extremely impressive, very few people actually need a sensitivity level of that magnitude. However, it shows that Razer is willing to push the limits of technology, and the general consensus is that the higher the DPI, the more accurate the mouse. The Focus + also offers 650 IPS, i.e. inches per second, which indicates the maximum speed at which you can move the mouse before the tracking starts to lose its accuracy. This means that you can move the mouse in a faster, more sudden manner, without diminishing precision, which is something we think will be far more important than DPI sensitivity for the average gamer.
Once again, the whole thing can be tuned via Razer Synapse, which remains among our favourite apps on the market. There are plenty of settings to tinker with, and it's all very straight forward to use, and even more casual gamers will find things to ponder.
The Razer Viper Ultimate is expensive, but at the same time, we think it's the best mouse on the market right now, and that goes some way towards justifying the extra expense. It might sound harsh, but from now on, if money is no option and you're after the very best, we don't see a reason to buy a G Pro Wireless or a G502 Lightspeed over the Viper Ultimate, and that's the highest praise we can give Razer's latest gaming mouse.
