Once you've verified the specs, the next step is to test the device yourself. Vape it, measure the actual number of puffs, and compare it to the stated count. If you're buying wholesale, request a sample batch and run your own checks.

You can also use tools like the Vape Cost Calculator to estimate the cost per puff, which is useful for pricing and cost-compliance analysis.

If you're dealing with specific issues like gurgling or leaking, check our guides on why vapes gurgle or leak and why vapes spit. Those issues often trace back to design flaws that compliance checks should catch.
