RandM is the flagship disposable e-cigarette brand under Shenzhen Fumote Technology Co., Ltd., co-founded by brothers Yang Kaiwen and Yang Kaiwu together with Chen Xiaochuan in early 2020. While it did not invent the disposable e-cigarette, RandM pioneered the disruptive product format of ultra-high-puff-count rechargeable disposables. This innovation extended the usage lifespan of disposable vapes from mere days to several months, significantly lowering the total cost of ownership for end users. Leveraging its exceptional cost-performance ratio and rapid product iteration cycles, RandM briefly ranked as the world’s second-largest disposable e-cigarette brand between 2022 and 2023, cementing its status as the undisputed dominant player in price-sensitive markets.
