Given how saturated the gaming mouse market has become, new names in particular have an increasingly hard time to get noticed. One such name is LAMZU, the Atlantis being their first release altogether. Of course, the easiest way to stand out from the competition is to release a stellar product, and that is exactly what LAMZU has done with the Atlantis.

What is immediately noticeable about the Atlantis is its weight. At 55 g, the Atlantis is among the lightest wireless mice available, especially at its size. The Atlantis sits at the upper range of what may be called medium-size, ever so slightly larger than the otherwise comparable Endgame Gear XM1r. Much like Pulsar with their X2 and X2 Mini, LAMZU does not resort to externally visible holes on the Atlantis, and instead has large cutouts on the bottom plate. More importantly, the mechanical design of the Atlantis is excellent, as despite the low weight and non-solid bottom plate, creaking or flexing are virtually nonexistent. Actuating the side buttons by squeezing the sides is impossible, and there is no rattle when shaking the mouse either, as the buttons are perfectly firm and stable. Speaking of which, LAMZU also went a different route for the buttons. Lately, Kailh GM 8.0 switches have become the de facto standard main button switch choice, being virtually ubiquitous. On the Atlantis, blue shell Huano switches are used for the main buttons instead, whose response isn't as sharp and mechanical as Kailh GM 8.0, yet still snappy, some pre-travel notwithstanding. For the side buttons, Kailh switches are indeed used, which have pleasingly little pre and post-travel. I have been informed by LAMZU that from the second batch onward, Huano switches will be used instead, as user feedback indicated the Kailh switches as too loud. Much like on the Pulsar X2 and X2 Mini, the encoder comes from TTC, again delivering tactile scrolling at elevated noise levels. As for the feet, LAMZU is using higher-quality skates than those found on the X2 or X2 Mini, and which appear to have very little to no dye added, resulting in pristine glide. What's more, a set of replacement feet is also included in the box.

When it comes to the internals, LAMZU has opted for the same combination of PixArt's latest PAW3395 sensor with the CX52850 MCU also found on the X2 and X2 Mini. Accordingly, performance as excellent, as one would expect. There is no CPI deviation whatsoever, general tracking is great, owing to MotionSync, polling is stable aside from polling rates below 1000 Hz in wireless mode, and motion delay low across the board due to a thorough lack of smoothing. Much like on other mice using this MCU, MotionSync does add some minor motion delay in the range of 0.5–1 ms, which results in a wireless motion delay of around 1.5–2 ms, though this is still perfectly competitive and therefore not meaningful in any way. Click latency is roughly 3.9 ms in wireless mode when using the lowest debounce time setting of 0 or 1 ms. As with other mice using this MCU, the first click after five seconds of button and sensor inactivity will be extended to a total latency of roughly 9 ms in wireless operation, provided the set debounce time does not result in a click latency equal to or higher than 9 ms in total. Note that this only applies when using the latest firmware, as on previous firmware versions, the Atlantis goes into sleep mode after five seconds of inactivity, resulting in a flat 9 ms of latency being added to the first click after. This is the same issue originally encountered on the Pulsar X2 and X2 Mini, but thankfully, LAMZU has fixed this, too.

The wireless experience in general is pleasing on the Atlantis. Charging is reasonably quick, and a wireless extender is included, although the charging cable isn't particularly flexible. However, the connector being angled upwards similarly to Zowie or VAXEE mice somewhat helps in this regard. LAMZU promises a battery life of 70 hours, which is within the realms of possibility given the battery capacity of 300 mAh, but since the battery indicator within the software is far from reliable or accurate, I have no way of confirming or denying this figure. Speaking of which, the software has all the relevant options at minimal resource cost, and I didn't encounter any bugs during use. Installing the software for initial setup at least is recommended to lower debounce time from the default 12 ms, which is way too high, and results in non-competitive click latency.

Overall, I am beyond impressed by the Atlantis. Even if it came from an established manufacturer, the Atlantis would be a stand-out mouse, but this being LAMZU's debut makes the Atlantis an even more remarkable release. Given the level of quality on display, the pricing is perfectly reasonable, too. Accordingly, the Atlantis rightfully earns our Editor's Choice.

When looking at alternatives, there is no shortage. The Razer Viper V2 Pro weighs virtually the same while also having no holes, has great performance, lower click latency, optical main button switches and high button quality, but resource-heavy software and a hefty price tag of $149.99. The Xtrfy M42 Wireless weighs more while having holes, has excellent performance, great buttons, and a swappable back cover, for $99.00. The $94.95 Pulsar X2 performs very similarly, weighs virtually the same at a smaller size, but the buttons can be hit or miss. For $89.99, the Fnatic BOLT has similarly great performance, slightly higher weight and no holes, and good main buttons, but suffers from its poor software and lackluster side buttons. The $79.99 Glorious Model O- Wireless scores in the click latency, weight, buttons, and charging cable department, but wireless motion delay is below par, and the software is a resource hog. Lastly, the Fantech Helios XD3 V2 is the budget option for $59.95, with great performance, very good buttons, and a big battery, but much higher weight, a stiffer charging cable, and lackluster side buttons.

Update March 2023:
When reviewing the Atlantis Mini, testing showed results differing from the original Atlantis in several aspects, and in particular in regard to latency added by MotionSync. Upon re-testing my sample of the Atlantis, I've found the mouse behaving weirdly; for instance, MotionSync was no longer enabled, even though disabling MotionSync isn't even possible in the software, among other non-matching behavior. To further investigate this situation, I have flashed the latest firmware for the Atlantis (November 2022) to my sample of the Atlantis Mini. Testing revealed that the latest firmware of the Atlantis (November 2022) and the default firmware of the Atlantis Mini behave identically. Hence, it stands to reason that my sample of the Atlantis may be bugged on a hardware level, and the results originally gathered with it may not be representative of expected performance. To remedy this, the review has been updated accordingly by including the testing in question performed with the Atlantis Mini running on the Atlantis firmware.
