Air Bar Diamond Pro Warranty and After Sales for Bulk Buyers
Published 2026 · VapeWholesaleHub trade desk

Warranty and after sales handling define the long term reputation of a Diamond Pro line.
Distributors reviewing their Diamond Pro range usually find that warranty and after sales explains most of the variance in results between accounts.
In practice the decision comes down to three numbers: unit cost, freight per unit and the realistic sell through rate for Diamond Pro.
Why warranty and after sales matters on the Diamond Pro
A clear dead on arrival policy removes friction for retail partners.
Where two suppliers look identical on price, warranty and after sales is usually the variable that separates them over a full year.
Spare parts availability matters more than warranty length in practice.
