The Phylina S480 Max directly competes with the SCYROX V6 in many ways: even though the S480 Max is slightly smaller, their shapes are almost the same, the weight is essentially the same (41 g as opposed to the V6's 42 g), the feature set is very similar (PixArt PAW 3950 sensor, 8000 Hz wireless polling), and at $69.99, the price is a match, too. Similarities also exist in terms of mechanical engineering: neither mouse resorts to weight-saving measures such as holes or an open bottom, but whereas the V6 achieves commendable structural integrity without any extra tricks such as an extended PCB, the S480 Max employs a larger plastic assembly also holding the side-button PCB, which is jammed across the width of the mouse to reduce shell flex. While this goal is largely achieved, the plastic piece itself isn't locked in particularly tightly, and will emit creaking noises of its own when applying significant lateral force. When shaking, there is no rattle, and actuating the side buttons by pressing below them isn't possible, either. Overall, the V6 emerges as the victor in the build quality department.

Whereas the V6 comes with optical switches from Omron, the S480 Max utilizes mechanical switches from Huano, more specifically of the blue transparent shell, pink plunger variety. Typically, these deliver firm and snappy actuation, but on the S480 Max, the button design leaves something to be desired. The main buttons have moderate pre-travel, which is compounded by the fact that before the switch proper actuates, a weird sort of pre-click happens, somewhat similarly to the Pulsar X2V2. Looking at the button mechanism during disassembly, I'm not sure what could be causing this, though it may be related to the post-travel stop gap, which indeed is effective at reducing post-travel to a minimum at least. Furthermore, the main buttons exhibit lateral movement to a moderate degree, although this only becomes apparent when actively provoked. The side buttons are likewise from Huano and surface-mounted. With these, the issue once again lies in their implementation. Whereas the forward button fares quite well, demonstrating low pre and moderate post-travel, the back button can be pushed into the shell in its entirety. In addition, and despite pre-travel being on the low side, actuation is very mushy and not pleasing at all. For the scroll wheel encoder, Phylina has opted for a brown/pink core from F-Switch, which exhibits high noise levels, and when scrolling down, a grinding noise is added, further compounding the noisiness. Tactility at least is quite good, as the individual steps have decent separation from each other. Similarly to the SCYROX V8, the S480 Max comes without feet installed. This is also how Phylina is able to arrive at the advertised weight of 36±2 g, though this still misses the mark slightly, as the S480 Max weighs 39 g without feet. The feet provided are of good quality, are made of pure PTFE, and glide well.

Aside from PixArt's latest PAW3950 sensor and a Nordic nRF52840 MCU for wireless communication, the S480 Max also employs an unspecified MCU providing a USB High-Speed PHY, enabling 8000 Hz polling in wired operation. From what I can gather, this is a rebranded Artery AT32F405 using the QFN32 package. In any case, performance on the S480 Max is in a good place. There is no CPI deviation at all, and general tracking shows no issues, irrespective of whether MotionSync is enabled or not. Polling is stable for the most part in that the target interval is averaged across the board, be it 125 Hz or 8000 Hz, wired or wireless. However, bouts of elevated variance are present throughout, although these do not amount to actually missed polls. The exception to this rule is 4000 Hz in wireless operation, which shows frequently missed polls on top of high variance. Somewhat interestingly, motion delay is the same between wired and wireless. Relative to the Logitech G403 (control subject), the S480 Max is ahead by 1.0 ms at polling rates at and above 2000 Hz without MotionSync, and still musters an advantage of 0.5 ms at 1000 Hz. Enabling MotionSync will add various amounts of motion delay depending on polling rate. This story continues when it comes to click latency, as 0.4 ms are averaged at the lowest debounce time setting regardless of polling rate, for both wired and wireless. Debounce time does not scale linearly on the S480 Max, though due to the presence of a slam-click prevention algorithm, one can run 0 ms debounce time no problem as long as there is no double-clicking. However, said algorithm is flawed in that after lift-off, the first click on landing will still have the full latency added to prevent slam-clicking applied, which amounts to ~18 ms. Obviously, this is not desirable both in terms of consistency and absolute latency. Given that the solution provider for the S480 Max is the same as the one for the LAMZU Maya X, this issue emerging once again is not surprising, though on the Maya X at least, it did get fixed in a firmware update. Of note is that jitter at the maximum CPI step of 30,000 is unusually high without ripple control, which has also been observed on the Maya X.

The software for the S480 Max is already familiar from the MCHOSE AX5 Pro Max. Similarly to the configuration utility for the latest Endgame Gear mice, the software is a self-contained application not requiring installation. All relevant settings are present, and I haven't found any noteworthy bugs. The only flaw would be the battery charge indicator, which lacks a percentage and instead uses segments, which isn't all that helpful. In addition, Phylina makes no indication of expected battery life, so how long the S480 Max ultimately lasts is anyone's guess. As an alternative to the self-contained application, the S480 Max can also be configured through a web driver, which connects through WebHID and therefore will, at least as of now, only work on Chromium-based browsers such as Chrome, Edge, and Opera (desktop). Functionally, the web driver is identical except for the battery life indicator, which also shows a percentage, though I didn't have any luck with that one either. Charging speed is average, but the stiffness of the charging cable makes playing while charging a rather arduous ordeal, not to mention that it also renders 8000 Hz wired polling more of an on-paper feature, since the cable is simply too stiff to facilitate pleasant wired usage. Bluetooth connectivity being present is a nice addition, however.

Overall, the S480 Max is not a bad mouse, though certainly marred by its underwhelming buttons and scroll wheel. Core performance is solid, but the same is also true of the SCYROX V6, and that one has no button issues and costs the same $69.99 the S480 Max retails for on Mechkeys.com. Given the choice, I'd always opt for the V6 over the S480 Max, as it has the same strong points yet none of the latter's weak points, and things such as shape or weight are no different. That said, an argument can be made that the PAW3395 variant of the S480 Max, which costs only $55.99, is a sensible budget alternative to the V6.
