“I have had this thing for years, I have updated to every Json file and firmware file I can find and it has NEVER worked right, Either the Json file or the firmware is jacked up and no one at Epomaker can give me any explanation. This numpad is the reason I…”

Epomaker EK21 vs Yunzii YZ19: your questions
The Epomaker EK21 supports VIA software, allowing for extensive key remapping, macro creation, and knob function customization. The Yunzii YZ19 listing does not mention VIA or similar advanced programming software, suggesting more limited customization options.
The Epomaker EK21 specifies a 1000Hz polling rate in its wired and 2.4GHz wireless modes. The vendor description for the Yunzii YZ19 does not provide a polling rate specification, so a direct comparison cannot be made.
The Yunzii YZ19 has a larger 1500mAh battery, while the Epomaker EK21 uses a 1000mAh battery. Based on capacity alone, the YZ19 should offer longer usage time between charges, assuming similar power efficiency.
The Epomaker EK21 is listed as hot-swappable and compatible with 3-pin and 5-pin switches, so you can install aftermarket tactile switches. However, the pre-built configurations shown only include linear switch options.
The Epomaker EK21 uses Cherry profile PBT keycaps. The Yunzii YZ19 uses XDA profile PBT keycaps, which are typically lower, uniform in height, and have a larger surface area than Cherry profile caps.
The Epomaker EK21 listing provides more modding details, including a polycarbonate plate, a flex-cut PCB and plate, and three specified layers of sound-dampening foam (Poron and IXPE). This makes its internal construction and modification potential more transparent.
Yes, both the Epomaker EK21 and Yunzii YZ19 list compatibility with Mac and Windows operating systems in their specifications.
South-facing RGB refers to LEDs positioned at the bottom of the switch socket. The Yunzii YZ19 specifies it has south-facing RGB lighting, which can reduce interference with certain sculpted keycap profiles. The Epomaker EK21 listing does not specify LED orientation.
The Epomaker EK21 vendor description states it has "pre-lubed and finely-tuned" plate-mounted stabilizers. The Yunzii YZ19 description does not mention the state of its stabilizers.
They are very close in footprint, but the Epomaker EK21 is slightly lighter at 200g versus 219.5g for the YZ19, and thinner at 29mm versus 41mm. The YZ19 counters with a larger battery for longer untethered use.
The Yunzii YZ19 description states the knob can adjust RGB and volume, but it does not mention software-based reprogrammability like the Epomaker EK21 offers through VIA.
