At their core, the Endurance and Shift series are nearly identical in style, specs, form, and function, but Endurance offers some improvements and also added some additional models.
Here is a short list of the enhancements and additions.
All models:
• Improved front panel access design, which makes them a lot easier to service in case of malfunction.
Non-Caged Endurance:
• Accommodates atomizers like the Taifun GT4 which is 25.5mm at its widest point.
Caged Endurance:
• Slightly shorter 510 drop/recess which make them more suitable for some of the shorter atomizers in your arsenal. 35mm -18650 / 40mm -21700
• Adjustable 510 which helps with perfect airflow positioning
• Cage to protect the atty or just for aesthetics.
Note:
• Max diameter of the Caged version is 24.3mm
Max diameter for non caged versions is 25.5mm
• 18650 mods have a Carbon Fiber Tube, whereas the 21700 mods have an open battery design.
