I appreciate the recommendations for both product and vendor - but I can't find a link to a Riva Ego on the Liberty Flights site. I see a Joye Ego, and some Riva branded products, but no Riva Ego. Am I missing something?
Riva is an Ego clone but with a slightly higher voltage that can handle lower ohm cartos.
The Kgo is very similar to the Riva. (larger batteries and higher voltage)
For something kinda larger but with relatively inexpensive batteries there's the E-Power. (more like a cigar)
E-Power Replacable Battery kit!
