Start with how you plan to use it. High-puff devices are better for longer use, while smaller models are easier to carry and more suitable for first-time testing.

Price differences usually come from puff count, battery size, display features, airflow design, and overall product positioning. Some models are designed for casual use, while others are better suited for repeat purchase or wholesale.

Not always. A higher puff count usually means longer use, but it may also come with a larger device. The better choice depends on whether you value portability, convenience, or longer-lasting performance.

Retail is better if you want to test products or buy in small quantities. Wholesale is more suitable for repeat buyers, store owners, or resellers who already know which models fit their customers.
