Wismec Reuleaux series  are all with the same size and similar exterior appearance, so you can have the similar touch feeling, is it the case? You can still notice the subtle difference, such as the display screen size. Reuleaux DNA200 is featured with the 0.91inch screen, but not the brand-new interface employed on display screen like on Reuleaux RX200S.  The new RX200S is equipped with the 0.96inch screen, more convenient and clear to display the vaping information.  However, the DNA200, powered by DNA200 Technology, really brings you so dinstinctive temperature controlled vaping experience at different temperature settings.
