Even though the shape of the Logitech G403/G703 is still popular, Logitech thus far has passed on the opportunity to release a modernized, lightweight successor. Naturally, it comes as no surprise that other manufacturers seize this opportunity by stepping in with products of their own. Teevolution is one of those companies, and the Terra Pro is the first release of theirs that goes beyond offering Fantech products under a different name. The shape of the Terra Pro is as close to the G403/G703 as it possibly can be, save for some largely aesthetic differences. Even seemingly minor details such as the curvature of the main buttons, size of the side buttons, and position and size of the scroll wheel have been recreated most faithfully. Much like Logitech's designs, the Terra Pro features a completely solid shell, without any holes or an open-bottom design. Yet, despite that and its low weight of 51 g, build quality is solid on my sample. When shaking, a slight rattle comes from an indeterminable location, but when applying lateral pressure, there is no creaking or flexing of the shell, and the side buttons cannot be actuated by pressing below them, either.

One of the greatest perks of the G403/G703 have always been their buttons, and the Terra Pro continues this tradition. To facilitate main button feel, the main button switches and scroll wheel encoder have been placed on a separate PCB, minimizing differences in tolerance in the process. For the main buttons, optical switches from FE are used, which share their pinout with the Omron D2FP-FN2, but provide much lighter, yet still snappy actuation. While I still slightly prefer how the mechanical Omron switches used on the G403 feel, these are reasonably similar in terms of feel and actuation force, and mainly differentiated by their higher and overall moderate level of pre and post-travel. Although many manufacturers opt for smaller surface-mounted or low-profile switches for the side buttons to save weight, Teevolution instead has opted for full-size mechanical switches, which no doubt is a wise choice given the footprint of the button pieces themselves. The actuation point is even across the entirety of these, and even though the forward button has a bit of pre-travel and both moderate post-travel, actuation is quite pleasing. The scroll wheel encoder comes from F-Switch, more specifically the brown/pink core variant, and delivers relatively low noise levels and an average level of tactility, as the individual steps are decently well-separated from each other. A less than ideal choice is presented by the feet. For whatever reason, these feature a pattern consisting of raised circles, which really does nothing except increase friction and worsen glide. The replacement set has the same pattern, but thankfully, a set of dots is included as well, which alleviates this somewhat at least.

By default, the Terra Pro comes with a regular USB full-speed wireless dongle, therefore limiting polling rate to 1000 Hz. Unfortunately, this base variant comes without a wireless extender, which is less than ideal given plugging the dongle directly into a USB 3.x port may result in interference adversely affecting wireless operation, and given how most motherboards mainly feature ports of this type these days, this presents a certain inconvenience. The sensor is PixArt's PAW3950, albeit with an extended CPI range and an added "STRIKE" moniker. The MCU is a Nordic nRF52840, and the firmware/software solution comes from CompX, which is why performance is largely within typical expectations. CPI deviation is minor and easily corrected, general tracking shows no issue regardless of whether MotionSync is enabled or not, and polling is generally stable across the board. Motion delay at 1000 Hz in wireless operation is the same regardless of which sensor run mode is used, and trails the Logitech G403 (control subject) by a little more than 0.5 ms without MotionSync. Click latency sits at 1.1 ms on average in wireless operation, though this only applies with debounce time set to the lowest value of 0 ms. Given that a flawless slam-click prevention algorithm is present, there is no reason not to use 0 ms, however, as double-clicking due to wear and tear is inherently impossible.

Available either as a separate purchase or in a bundle, the 8K Dongle turns the Terra Pro into a USB high-speed device, enabling polling rates above 1000 Hz, all the way up to 8000 Hz. While performance at polling rates of 1000 Hz remains largely the same, as motion delay is unchanged, and click latency now averages 1.0 ms at a debounce time of 0 ms, higher polling rates do cut down on latency. In terms of motion delay, the Terra Pro at 8000 Hz and without MotionSync will be ahead of the G403 by 0.9 ms, and in terms of click latency, 0.8 ms will be averaged at a debounce time of 0 ms. Compared to other CompX solutions, click latency at least stays worse than expectations, as the Hitscan Hyperlight or SCYROX V8 manage an average of 0.4 ms at 8000 Hz. Polling stability, however, deserves a positive mention. The target interval is averaged across the board, including at 8000 Hz, and off-period polls are very rare, resulting in highly stable polling, aside from the odd instance of elevated noise. Overall, the 8K dongle provides a decent performance improvement, especially for motion delay, though one has to actually use polling rates above 1000 Hz to get the full benefit, as 1000 Hz essentially does not benefit at all. A bit of additional usefulness is provided by the 8K dongle in that the built-in screen can display either currently active settings and battery percentage or the time and date. In principle, this is similar to the receiver of the Arbiter Studio AKITSU, albeit at a higher display resolution and with more extensive functionality.

In terms of configuration, the Terra Pro leaves the choice to the user. One can opt either for the lightweight software, which has all relevant options, is largely bug-free, and uses little resources, or the web driver, which basically is a server-hosted, functionally identical version of the software, connecting through WebHID and therefore being restricted to Chromium-based browsers such as Chrome, Edge, or Opera (desktop). The software will only display a battery percentage if a line in the configuration file is modified, whereas both the web driver and the 8K dongle displays readings in increments of 5%. At 8000 Hz, the indicator went down by 20% for every 2.5 hours of continuous usage, which would amount to around 12 hours of expected battery life in total. At 1000 Hz, this would translate to around 60 hours, which isn't too far off the 70 hours cited by Teevolution. Charging is decently speedy on the Terra Pro, which is good given that the charging cable is fairly short at 1.5 m and, more importantly, genuinely stiff, preventing playing while charging almost entirely.

The Terra Pro is offered in two different variants. The base variant comes without the 8K Dongle and is priced at $79.80. Given that a comparable competitor such as the SCYROX V8 retails for $69.99 while already including an 8K dongle, the Terra Pro doesn't compare too favorably. Bundled together with the 8K Dongle, the Terra Pro costs $105.80, which is on par with the Hitscan Hyperlight, which isn't exactly bargain territory, either. At the same time, those loving the G403/G703 shape likely won't mind paying the premium for the Terra Pro just to get their hands on that shape again. Furthermore, at least until the funding campaign for the Terra Pro on Indiegogo.com has not concluded, the base variant is available for just $59.80, and the 8K bundle for $79.80, which is genuinely good value. Still, even at the non-discounted prices, the Terra Pro finally delivers on the prospect of a lightweight, high-quality G403/G703, and earns our Recommended award.
