I am considering the "upgrade". Is the Vamo a good place to start, in your opinion? (Keep in mind I've only owned egos). Will my evods and Kanger T2s fit on the Vamo?
Lastly.. Is there a real significant difference in the flavor and vapor production when you upgrade?
The Vamo is excellent, and you can get into a kit for $50, which is half what I spent on a cheap Ego clone kit at my local B&M store (of which I use NONE of the parts anymore).
Twists and Spinners are great too and offer a much more streamlined form-factor for travel. However, when they die, you'll need to replace the whole battery, and now you've spent the same amount as the Vamo kit.
Most importantly, the EVODs and T2s will fit the Vamo as it has both 510 and Ego threads. However, the ego threads are recessed a bit so you "could" unscrew the clearo tank from the base by accident, spilling the juice. You'd do well to pick up a couple 510-to-Ego adapters, for a couple $$s each. This will raise the tank a little so you can grasp the base of the tank when removing.
And finally, yes, since you'll be able to adjust the voltage and/or wattage, you'll be able to fine tune your flavor and vapor hit, whereas your egos are fixed voltage.
Vamos=very good; get adapter for EVODs or any BCCs; dont need adapter for ProTanks or Vivi Novas; get one big battery 18650 and 2 little batteries (18350s) so you can use the Vamo in shorty mode.
Hope it helps.
