It's amazing how many people don't realize that the Riva really isn't better than an egoIt's only better for maybe the first 30 minutes of vaping (depending on mah of the batt), after that the voltage drops below the constant voltage of the ego and just goes down from there.
I agree somewhat. The last hour or so on a Riva battery is not as good as the last hour on an eGo. However, during the first 50-75% of the charge the vape is hotter on the Riva. When the vapor starts dropping in quality you can just stick the battery back on the charger without affecting the battery's longevity. I, personally prefer having the "hotter" battery even if it means that I don't get as much use out of it as if I was using a regulated eGo battery. I am not saying that one is better that the other - it all depends on what you want and what works for you.
