Honestly, lotus all the way, got mine about 2 months ago and it fully destroys my DBV, solo, wychwood vape, frankly I HATE having to hit the DBV after the lotus. The lotus is BAM its fast you can vape the whole load in about 2 hits and it gives a waaaay better hit than the DBV. You can add as much heat as you want, its seriously a really neat piece of design. Plus a can of tane lasts just about forever versus batteries.
I was skeptical buying it as it seemed expensive for what you get but nowadays I just cant imagine not having it, its hands down the best vape I've used in terms of speed, extraction, portability, and most importantly, getting you really really high.
