So I currently own an Air, Iq, Cloud Evo, and a plenty (which I rarely use now); omni vap is my next investment. My current concern is the safety and risk factor of some of the materials used in those vapes. The air has a rubber ring that holds the stem. The IQ has a silicone gasket and ring (bottom of flavor chamber). The Omni/dynavap has silicone o-rings. The cloud evo uses steel baskets. The plenty has some much plastic involved in its air path. I understand that much of these products/companies use high quality materials but with consistent and high usage of these vapes (many sessions a day for hopefully years), do those materials/components pose any potential risks/hazards? Thoughts? These are products that utilize high temps, electricity, and tons of usage. Thanks!!!
