• Online-only vape retailers need a different comparison-test playbook than physical shops. Instead of relying on in-store feel, you verify specs, sample batches, and mine customer reviews for patterns. This approach catches reliability issues early and builds trust with buyers who can't inspect products before purchase.
• Verify battery and puff-count specs against independent teardowns, not just the box.
• Sample multiple units from different batches to catch quality drift.
• Track customer complaints about leaks, charging, and coil taste to prioritize fixes.
• Use calculators and community forums to cross-check performance claims.
