David Cho is the Smart Yard Editor at YardToolLab, where he brings six years of hands on experience testing robotic mowers, smart sprinklers, and connected yard tech. He entered this niche after a decade in smart home automation, where he wired and programmed whole house systems. Frustrated by vague marketing claims for outdoor gear, he shifted his focus to the lawn. Today, he runs a fully automated yard that relies entirely on the tools he reviews. Readers trust him because he does not invent lab results. He installs each mower, configures every app, and tracks real world performance over full seasons. His honest, research based approach cuts through hype to show what actually works for a connected landscape.
