🏭 Industrial Prototyping Team Review

⭐⭐⭐⭐☆ Marco Santos - R&D Prototyping Lead
"We’ve been testing the Advanced Model in our new sensor array design. The +15% light intensity helps with visual diagnostics on densely packed boards. Only reason I’m not giving 5 stars is that handling requires precision tools due to the 0402 size—fine for automated assembly, but tricky for manual soldering."
