Kysona has recently made a name for itself in the ultralight wireless gaming mouse space with the launch of the Uranus Pro, and now it is following that launch up with the Mercury series, headed up by the Mercury Ultra, which packs a PixArt PAW3950 sensor, a 41 g weight with no holes, and Omron Optical Micro switches, which should be good for 70 million clicks. The Mercury Pro and Mercury SE both also feature similarly lightweight designs and identical dimensions, with lower pricing and slightly altered internals. The Mercury Ultra carries a $69.99 MSRP and $49.99 launch price, while the Mercury Pro is $49.99 but $32.99 at launch, and the Mercury SE is $29.99 with a $21.99 launch price. Currently, it is only available via the Kysona online store, but Kysona’s products have previously been available on Amazon, so that seems like a matter of time, too.
Kysona says the Mercury is built for smaller hands, measuring in at just 118×63×38 mm, and it features a similar shape to the Pulsar X2 Crazylight we recently reviewed, albeit with some slight tweaks to the curvature on the sides and a slightly heavier weight of 41 g, measured without the skates. The Mercury SE weighs in at 40 g, which is 1 g lighter than the Mercury Pro and Ultra. The Mercury Ultra features Omron optical switches and a PAW3950 sensor, while the Pro and SE have Huano mechanical switches—100 million “transparent white” and 20 million “blue shell white dot,” respectively. The Mercury SE also drops the 8 kHz polling featured in the Ultra and Pro versions and uses the PAW3311 sensor, while the Mercury Pro maintains 8 kHz polling with a PAW3395 sensor. Curiously, the Ultra and the SE share the same 300 mAh battery capacity, while the Pro version steps it up to 500 mAh. All three mice also feature both Bluetooth and 2.4 GHz wireless connectivity, with wired USB Type-C as an option as well. All three mice also have the same five buttons (including scroll wheel click), and they are all remappable with macro support, although only the Pro and SE support a web driver, while the Mercury Ultra requires the installation of software—which has recently been proven to be suboptimal.
