Model Group Best For Pros Cons
Classic Straight Stems (70mm & 110mm) Pure & Simple Baseline Exact replicas of the original manufacturer glass; delivers the pure flavor and familiar restricted draw you are used to. Standard 4-hole airflow design is low airflow
The 'Aero' High-Airflow Stems (70mm & 110mm) Easier, Smoother Pulls The upgraded high air flow design significantly reduces draw resistance, making inhalation feel completely effortless. The greatly increased airflow can result in slightly less dense clouds if you pull too fast.
The 'Aero' XL Deep-Fill Stems Cloud Chasers Combines the easy-pull 'Aero' airflow with an expanded XL herb chamber for truly massive, long-lasting vapor production. Requires packing more herb per session, plus require screen filters. 
The Angled Stems (Classic & Aero) Relaxed "Couch" Sessions The ergonomic bent mouthpiece allows you to keep the vaporizer completely upright while bringing the vapor comfortably to your lips. The bend makes them slightly less pocket-friendly and harder to swab out than a straight tube.
The 'Stealth' Micro Stem (40mm) Ultimate Portability Extremely compact size turns your Arizer into a highly pocketable, ultra-discreet device for on-the-go use. The very short vapor path means noticeably warmer vapor compared to longer stems.
The 'Onyx' Black XL Shaded Stem Discreet Style Features a beautiful dark aesthetic that naturally hides resin buildup between cleanings, alongside the upgraded XL herb chamber. The dark glass makes it slightly harder to visually check if your herb is fully extracted compared to clear glass.
The Classic 'Pro' Master Stem Kit Total Versatility The ultimate bundle giving you a variety of essential stems and screens for a perfect daily driver. Classic but slightly boring stems - great as a backup or those on a budget.Â
