They do look nice, but not the size of my ego. My biggest problem now is I use to just use some cash to buy cigs or the cost was included in gas cost. Not broken out into x amount for this and that. Now the cost is on the credit card and the wife is counting and letting me know about every penny. Comes down to You spent How MUCH$$$. What makes you think you are saving-----
Your Ego e-cig or your ego? The Riva is the same size if not a bit bigger than the Ego 650mah. It's 750mah. I have an Ego 900mah battery that's bigger than both.
As to the cost, I don't have anyone else that I'm accountable except to myself, and it's very hard to say No to someone you love (like myself to myself)!
