I am a heavy vapor, and I was getting really tired of my KR808D-1. Not enough vapor production...switching batteries every hour or 2...nasty tasting cartomizers...really tight draw.

I got a Riva 510 and I can't believe what a difference there is!!!! 

Tons of vapor, Better flavor than I ever got with the KR, and a really, really easy draw (the hard pull on my automatic KR batts and turbo carts was killing me...WAY too much work!!!)
With my Riva, I push the button, and I get huge plumes of great tasting, cool vapor with almost no effort!!!
Yes, I know that I have to refill more often, and keep extra attys on hand, but who cares!!!! There is maintenance with every e-cig.
The point here is that this is exactly what I was looking for when I ordered my KR in August...But I found it in the Riva 510!!!!! It's also smaller and better looking than I thought it would be!!
I recommend the Riva to anybody looking for a really great vape!!!
