I have the Evo and the 510 and I love them both for different reasons.
My only problem with the Evo has been some leaking of liq into my mouth but surprisingly I haven't had this problem for the last 3 or 4 days so not sure whether my new batch of carts have been filled better; the evo is working better; or, I'm getting used to it more?
I think I drew too hard on it at first.
Now if I feel a drop coming out I immediately wipe the end then take the inner cart out and wipe all of that clean before finally blowing
through the cart to get any other excess liquid out.
It is a very smooth, pleasant and nice smoke! Consistent vapour and taste. I think you'll love it and the ecopure liquid is amazing. I can also get a nice long draw from the evo too so not sure whether it has an automatic cut off longer than others or maybe when I dropped it a couple of times in the first few days broke the cutoff?!
Got mine from intellicig in the UK.
