Introduction

Founded in 2020, Pulsar is a gaming peripherals company based in Korea. Typically, the "eS" moniker denotes variants of already existing Pulsar mice that are specifically catered towards professional play. The eS FS-1, on the other hand, has no non-eS counterpart, which is unsurprising given that it results from a cooperation between Pulsar and VAXEE, as VAXEE's entire design philosophy is centered around competitive viability. Still, the 59 g, solid-shell eS FS-1 is primarily a Pulsar mouse, which is underlined by the fact that it is fully integrated into the Pulsar ecosystem. As such, the eS FS-1 is equipped with Pulsar's XS-1 sensor capable of 32,000 CPI, which is a customized PixArt PAW3950. The main buttons are outfitted with Pulsar Optical switches rated for 100 million actuations. Notably, the scroll wheel is made out of a steel alloy. Polling rates of up to 8000 Hz are supported in both wired and wireless operation, and Pulsar claims up to 160 hours of battery life, albeit without specifying polling rate. Configuration is done either in software or conveniently through a web driver.

Specifications

Packaging

Aside from the mouse, one finds a USB Type-A to Type-C cable, wireless dongle, collector card, sticker, and quick start guide inside the box.

Weight

My scale shows around 59 g (±1 g), which is roughly in line with the weight cited by Pulsar, as that one does not include skates. For comparison, the similarly sized and likewise solid-shell VAXEE XE V2 Wireless weighs 59 g, whereas the also similarly sized and solid-shell RAWM Leviathan V4 weighs 53 g. A very good weight.
