🖥️ Data Center Infrastructure Review

⭐⭐⭐⭐☆ Marcus Reed - Data Center Hardware Lead
"We tested the Pro Model in a high-density server rack transformer array. The dual-layer coating handled coolant exposure without issue, and thermal stability at 190°C is impressive. The ±0.5% tolerance ensures consistent magnetic coupling across units. Only downside: slightly heavier than expected, which affects large-scale deployment logistics. Still, worth the trade-off for reliability."
