Introduction
Founded in 2019, RAWM is a peripherals company based in China. Even though it sits somewhere between the LAMZU Maya and Maya X in size and has a fully solid shell, the ES21M weighs no more than 47 g. PixArt's latest PAW3950 sensor capable of 30,000 CPI sees use, along with Huano switches of the green transparent shell, white plunger variety for the main buttons. Polling rates of up to 8000 Hz are supported in wireless operation, and RAWM cites up to 21 hours of battery life using 8000 Hz, and up to 85 hours using 1000 Hz. The feet are made of pure PTFE, and a set of grip tape is included in the box. Configuration is possible either through a web driver or a desktop application requiring installation, both of which are self-developed by RAWM. The ES21M is available either in black or white.

Weight
My scale shows around 47 g (+/- 1 g), which is in line with the weight cited by RAWM. For comparison, the SCYROX V8 weighs 40 g while being smaller and having a solid shell as well, whereas the LAMZU Maya X employs an open-bottom design, is larger, and weighs 48 g. An excellent weight overall.
