Recently been looking round at dual battery squonkers for a bit more battery life than the Pulse 80. Came down to a toss up between the Nikola Niagara and the Rage. Both have little niggles I'm not that keen on though. However, recently contacted lost vape who confirmed they are releasing a new Drone 250 around September / October so will likely hang on for that to see how it stacks up against the competition.
