It took a while, but at last, Razer gave their DeathAdder the wireless treatment. Having tested the Viper Ultimate back in 2019, I expected this to be a fairly straightforward review, but that turned out to only be partially true.

The DeathAdder V2 Pro utilizes Razer's latest Focus+ sensor to great effect. Owing to MotionSync, tracking is virtually flawless, polling rate stability rock-solid, and sensor motion delay nothing short of excellent, both in wired and wireless operation. Coupled with the low latency afforded by Razer's optical main button switches, general performance is great across the board for but one caveat. My testing suggests wireless motion delay—the latency added by wireless transmission—to at least be 2 ms at all times, which is double that of the Viper Ultimate. Of course, I got suspicious and went back and re-tested both the Viper Ultimate and Logitech G Pro Wireless, but both still showed the expected 1 ms delay. Testing the second DeathAdder V2 Pro sample didn't yield different numbers, either. Naturally, I informed Razer about my findings, but they couldn't reproduce or verify my results. Although I'm confident in my testing, it's entirely possible that there is an external unaccounted factor that negatively affects the wireless connection of the DeathAdder V2 Pro at my place. In conclusion, I have to settle for the assertion that it's at least possible for the DeathAdder V2 Pro to have higher wireless delay than the Viper Ultimate, but I have no way to tell for sure. Either way, the added delay still isn't what I would call significant, and sure enough, I wasn't hindered in-game to any degree, so I'm inclined to call it a non-issue.

Aside from this motion delay discussion, general wireless performance is just as good as on the Viper Ultimate. Battery life is strong, and the highly granular battery indicator makes it easy to tell when the battery is running low. Aside from wired and 2.4 GHz operation, the DeathAdder V2 Pro is capable of Bluetooth as well, allowing for even longer battery life, which makes the V2 Pro a great fit for traveling as it also includes a compartment for the wireless dongle. At home, the DeathAdder V2 Pro can also be used with the Razer Chroma charging dock, which is the most convenient way of charging it. Alternatively, one can use the included charging cable, although that one can't compete with the charging cables on the ASUS ROG Keris Wireless or Glorious Model O Wireless in terms of flexibility. Much like other recent Razer mice, the DeathAdder V2 Pro also comes with pure PTFE feet, which glide very nicely indeed.

At 87 g, the DeathAdder V2 Pro only weighs 5 g more than its wired counterpart, which is nothing short of impressive. Build quality is solid as well with barely any creaking or flexing, and actuating the side buttons by squeezing the sides is impossible. Speaking of which, the side buttons are among the best I've seen on a mouse: Even actuation across the entirety of these, minimal pre and post-travel, and a snappy click response. The scroll wheel is similarly good with clearly separated steps, and not too noisy. The same cannot be said about the main buttons, however. The first copy I received has a notably poor right button with mushy feedback, a muted click response, and just a lackluster feel of quality overall. And sure enough, upon disassembly, the right button switch was significantly less "clicky" than the left one, pointing towards poor quality control and too much variance. The second copy presented itself much improved in this regard, and although the clicks still weren't my favorite, they're perfectly fine to use. Still, I simply expect more from a $130 mouse—luck of the draw when it comes to button variance isn't acceptable, and I hope Razer finds a way to tighten their tolerances and refine the button design to ensure good button quality no matter what.

Of course, the DeathAdder V2 Pro is fully compatible with Razer Synapse. In terms of functionality, I can't really fault Synapse, and it offers several settings seldom found elsewhere, along with a highly granular battery life indicator. But when it comes to the number of running processes and resource usage, there's definitively room for improvement. Synapse also allows one to configure the RGB lighting, which has been kept rather basic to keep battery life intact. For what it's worth, the RGB lighting can actually be used on the DeathAdder V2 Pro—unlike on the SteelSeries Aerox 3 Wireless, where battery life suffers greatly from enabling RGB fully.

This conclusion may sound more negative than it should. At the end of the day, there are only two notable concerns: The wireless motion delay, which is by all means a non-issue, and the main buttons, which can be hit or miss. From what I've seen, most people seem to be satisfied with the main buttons on their copies, so it's entirely possible I got unlucky in that regard. The bigger issue in that context is actually the price—$129.99 is already steep, and at that price point, one shouldn't at all have to worry about running into any button issues. This becomes quite apparent when looking at the competition. For $99.99, the ASUS ROG Keris Wireless too comes with triple connectivity, great sensor performance, and high quality in general, but it's a much smaller mouse and thus not necessarily an alternative. The ASUS ROG Chakram, on the other hand, is similarly sized, but even pricier at $159.99, and weighs quite a bit more, although performance and quality are on par. The ROCCAT Kain 200 is DeathAdder-sized as well, but has much worse performance, albeit quality is easily on the same level, for $99.99. Lastly, the Dream Machines DM6 Holey Duo goes for $49.99, but suffers from huge click latency and CPI deviation even though wireless performance is appreciable, and it's similarly sized, too. At the end of the day, if the main buttons are fine on one's copy, there really isn't much wrong with the Razer DeathAdder V2 Pro, which is why it gets our Recommended award from me.
