In the beginning, the USD (UP Side Down) RBA was based on the idea of making something different, something unique – a novelty in vaping. During the whole process of designing, prototyping, and testing CloudMods wanted to ensure that the project had the extra features that can actually boost the vaping experience.

It’s the first top-wicking RBA with 3 different options of liquid control pins. There are also 5 different air pins. That means there are a lot of different combinations of wicking and airflow that can help everyone find the best for every build! You can easily go from MTL to DL vaping, space on deck, wicking and airflow can easily support it! USD RBAs overall size perfectly fits in all OG Boros and most of the aftermarket ones, has a lot of space on deck for “heavy” builds, and still has a 4+ ml of liquid capacity in OG Boros. Keep in mind this is a new design, something totally different from the other RBAs in the market. Every user should take advantage of the features USD RBA provides and find the best built for their personal vaping style! USD RBAs design was not easy to produce. They knew that. Most of the parts need 5-axis machining, precision and quality control should be close to perfection!
