I edited the original post, I didn't want to offend anyone ha. Basically more what I meant is that the eGo or built-in battery kits are always suggested to beginners and I havn't read many "beginner needs advice" posts with people suggesting the Vamo. Me personally, the Vamo is a really simple device and I think it is a great mod for beginners. Again didn't want to step on anyone's toes and it is my suggestion that the Vamo can be a very good beginner device.
It can be a great device for beginners, but some people are put off by the size and are confused with the choice between VV and VW. Newer vapers might not like the idea of changing batteries, and may not know what type of battery they need and what choice of charger to get. The ego style batteries are a little simpler and smaller and you don't have to mess with changing batteries. I have a Vamo and a Spinner, they both have a place in my vaping style.
As for more advanced APV's, Vamo is the best bang for the buck, especially since you can get an entire kit from Fasttech for a song. No one choice is right for everyone, some like cigalikes, some like egos, some start out with a Provari.
