Recently, there has been a wave of new mouse manufacturers emerging from China, many of which have garnered attention for providing good quality at highly competitive prices. While Waizowl too hails from China, their emphasis lies more on quality. Their first release, the OGM Pro, also introduces a shape that isn't as derivative as others. Relative to its length, the right-handed ergonomic OGM Pro is noticeably wide, barely curving inwards on the left side in particular, and the left side isn't raised as much as on other right-handed ergonomic designs, either. Despite not being as large as a DeathAdder, its high profile along with a bulky body lend the OGM Pro well to larger and, more specifically, wider hands.

At 70 g, the OGM Pro isn't as light as the Razer DeathAdder V3 Pro at 62 g, for instance, but the build quality is on a very high level. My unit has no rattle when shaking, no creaking or flexing of the shell when applying lateral pressure, and activating the side buttons by pressing below them is impossible. The switches used for all buttons likewise are of high quality. TTC Gold switches rated for 80 million clicks are used for the main buttons, which end up accordingly snappy, and the button design is excellent, as lateral play is kept at a minimum even when provoking it. Kailh switches are used for the side buttons, which have impressively low pre and post-travel, along with an even actuation point. That said, due to the high profile of the OGM Pro and the side buttons not being that large, some may find these out of reach when trying to roll their thumb across them. Even the scroll wheel and CPI buttons have been outfitted with full-size mechanical switches from Kailh, further adding to the quality impression given by the OGM Pro. The scroll wheel encoder comes from TTC ("Gold"), and on my sample at least, tactility is seriously lacking, resulting in scrolling that is a bit too light for my tastes. When using the scroll wheel click in particular, scrolling unintentionally can happen often. White-dyed pure PTFE feet of above average thickness are used, which glide very well, and a set of replacement feet is included, along with a set of grip tape.

The wireless experience on the OGM Pro is pleasing. The charging cable is among the most flexible around, easily allowing one to play while charging without feeling restricted. Charging isn't particularly speedy at less than 0.2 A, but coupled with the flexible cable, this can be forgiven in my book. In terms of battery life, Waizowl cites 70 hours at 1000 Hz in 2.4 GHz operation, and even though the battery indicator found within the software isn't too reliable, I consider this figure to be within the realm of possibility. Bluetooth operation is also on board, allowing one to extend battery life even further for non-gaming purposes. Speaking of the software, some rocky translations aside, all the relevant settings are there, resource usage is low, and I haven't encountered any bugs during testing.

Performance is stellar on the OGM Pro. If set to the lowest debounce time value, click latency sits at just 1.5 ms in wireless (2.4 GHz) operation, which is only marginally short of the DeathAdder V3 Pro. The only downside in this regard is slam-clicking, which describes unintentional button actuation upon "slamming" or gently repositioning the mouse after lift-off, being reasonably easy to reproduce at the lower debounce time values. Higher values solve this, albeit at the cost of accordingly higher click latency. Sensor performance is on the same high level. CPI deviation is kept to a minimum, general tracking is fine, and all polling rates are fully stable across the board. Much like on other mice featuring the PixArt PAW3395 sensor, MotionSync is on board, which synchronizes SPI reads with USB polling events. As with most other implementations, enabling this comes with a motion delay penalty, amounting to roughly 0.5 ms at 1000 Hz. Without MotionSync, the OGM Pro manages a motion delay differential of just 0.5 ms, which is increased to a still formidable 1 ms with MotionSync enabled. Among regular 1000 Hz wireless mice, the OGM Pro therefore ranks among the very best, right next to the ASUS ROG Harpe Ace Aim Lab Edition and VAXEE's wireless offerings.

In summary, there is remarkably little to criticize about the OGM Pro. At $99.99 on Mechkeys.com, the OGM Pro is priced confidently compared to many other releases from Chinese brands, though the quality to match that pricing is undoubtedly there. If anything, it is support and warranty having a question mark to them, especially for buyers not from China. Still, for those willing to take this risk, the OGM Pro is a very solid choice. As such, it earns our Editor's Choice.
