How does the WHEELTOP EDS compare to Shimano Di2 or SRAM AXS in price and features?

The WHEELTOP EDS is priced around $339, significantly undercutting Shimano Di2 (~$600+) and SRAM AXS (~$700+) while delivering carbon fiber OSPW cage with 12T hollow carbon pulleys and app-based customization. Unlike Di2 and AXS which focus on road and mountain racing, the WHEELTOP EDS is purpose-built for flat-bar bikes, gravel, city, and e-bikes with reduced drivetrain friction compared to standard cages.
