I've been
vaping now for 15 days... bought my first from Vaporescense in Denton, Tx. When I came in, Greg (the owner) initially tried to steer me away from what I actually purchased which was the Joye 510... He seems to be (I should reword to IS) a very good judge of people - because he originally steered me towards the Riva. Well, 13 days later, and I was looking at the Riva when he got a shipment of eGo's in...
Looking at the two - there was really no difference whatsoever between the two. Talking to Greg, he said its really a toss-up between the difference in battery life... "Some say the Riva, Some say eGo" it all really depends on how you vape. I personally found the difference in button's really no big deal... what turned me onto the eGo - was simply that he had Stainless -- I just liked the look of it over the riva... Yup - Color was the difference for me.
Now, knowing a few others who bought the Riva - all I've heard is good things about it... I'm extremely happy with my eGo and the fact that everything is interchangable with my Joye just makes it even better for me. (The same thing goes for the Riva)...
I think choosing between the two - its all in a matter of what one you think fits you best. I was a pack a day smoker, switched to
vaping, and get a full day from my battery. I hear the same life out of a Riva owner I know... so that's my personal take on them...
