Xerall is a legitimate hardware startup producing the 'X-TankCopter' (flying tank drone), which demonstrates verifiable engineering innovation and patented technology. However, the project submission is extremely low quality, featuring hyperbolic and factually incorrect claims (e.g., 'most people have used my product', audience 'everyone'). While external search confirms crowdfunding success and niche sales (likely low thousands of units), the lack of concrete financial data, small scale relative to the broader market, and unprofessional submission heavily penalize the score. The project falls into the 'Minimal Traction' category with a score reflecting its niche hardware reality weighed against poor presentation.
