The OneUP SturdyONE Upgrade Kit from Sturdy MFG transforms your existing SturdyONE RBA with improved performance and enhanced flavour. This add-on kit upgrades your RBA with enlarged wicking ports for easier setup, a more compact footprint for denser flavour, and a fresh contemporary look. Compatible with SturdyONE RBA Batch 1, 2, and 3 - no need to buy a new RBA when you can upgrade what you already own. Built from 316 stainless steel with a black PEEK insulator for durability and heat resistance.


The OneUP kit refreshes your SturdyONE RBA without buying a whole new deck. Enlarged wicking ports make cotton threading faster and less fiddly. The compact design concentrates flavour for a more intense hit. The contemporary look updates your RBA's appearance. Works with all three SturdyONE batches - Batch 1, 2, or 3. Built from 316 stainless steel with black PEEK insulation. The OneUP kit improves performance and style in one simple upgrade.
