3 change(s): 2 major, 1 moderate | Durability score is low based on multiple user reports of sensor electrode degradation/detachment within 1-2 years, charger pin contact failures within months, and spontaneous device failures. Material quality score reflects these durability issues and design flaws in charging mechanism. Brand reputation signal is low due to warranty denial issues, deliberate feature downgrade perception, and a pattern of durability problems across multiple user reports. Original Fitbit Sense also criticized for bugs and software issues at launch.
