Software
Software-wise, this company has a lot of catching up to do. As mentioned before, out of the three tested devices, only the BD-01 was recognized by the driver software (of which I've downloaded four different versions for testing purposes). Testing was done on two separate PCs with two different Windows 10 versions. As far as I could tell, all of the company's mice have fully detailed tutorial videos for their software on their product pages, which is definitely a nice touch.
The software suffers from a ton of grammatical errors and doesn't look very appealing. However, usability is not really cut short by these drawbacks. It's pretty fast and very lightweight. It only downloads the modules necessary for the used devices, which is definitely a good thing. Once your device is selected, you are transferred to a single window that lets you fiddle with button mapping, profiles, and macros. By pressing the performance button, the page shifts to the CPI and polling-rate options.
Lighting
Out of the three tested EasySMX mice, the V50 has some proper RGB features, but I couldn't see all of them due to the software not recognizing the mouse. The lighting generally looks good; it's bright, with nice colors, but the transitions could be smoother.
I also made a video to demonstrate the stock effect:
