What RAWM's lineup looks like
RAWM is a gaming-peripheral brand that sells directly through rawmshop.com. Its mice share a similar idea: low weight, a PixArt sensor, a 2.4 GHz wireless dongle and a web or app-based driver (RAWM Hub). The differences that matter when you choose are the switch type, the maximum polling rate, the shape and the price.
On the store's own pages the brand lists a "Halloween Specials" promotion running October 15–31 with free shipping on mice, and the Leviathan V4 GT is highlighted in the navigation as a featured deal. Discount amounts change quickly, so read the price on the product page rather than relying on the figures below once the promotion ends.

Which one fits you?
Lowest weight: the ES21PRO is listed at 47 g, the lightest of the five, with the same PAW3950 sensor used on the Leviathan models.
Latest platform: the two Leviathan V4 models are the only ones advertising native dual 8K polling and a larger 45,000 DPI ceiling. The GT adds a dual optical/magnetic switch design, which the brand pitches as the headline upgrade.
Right-handed contour: the ER21PRO is the shaped model; the others are more symmetrical.
Tight budget or Bluetooth: the SH01S costs about half as much as the Leviathans and is the only one with Bluetooth, but it is the heaviest and capped at 1000 Hz wireless.
