Methodology v1.0
2 change(s): 1 moderate, 1 major | Durability score reflects widespread complaints about thin plastic construction with estimated 1-2 year lifespan. Material quality score reflects use of thin plastic casing with rain resistance but poor longevity expectations. Brand reputation signal reflects mixed feedback: early adopters satisfied but service quality decline noted over time (mentioned 5+ year decline), and questionable business practices around battery removal between generations to drive upgrades. Temperature range capability (-5 to 120°F) is acceptable but doesn't offset material concerns.
