Uwell has become popular for introducing the Uwell Crown, a sub ohm tank that is widely recognized as one of the best on the market. The first edition of Uwell Crown was a real game changer and, followed by Crown Mini, Crown II, Crown III, and now the Crown IV, it still stays very popular to this day due to its flawless design and a tremendous amount of effort put into research and development of this tank that had defined its success for years ahead. The Crown’s design encompasses improved airflow, high performance, ability to produce a flavor-rich vapor and compatibility with different types of mid-watt box mods.
