Like you, I am fairly new to vaping as well. Just curious, if this is your first 510 device, what have you been using until now? If it is KR808, would you mind comparing the two? (That is what I am using).
Guess it was my sig that gave me away, eh?
The lea seems to produce a much mouthier vapor using my primary vendor juice. I'm also impressed by the build quality, the threads are smooth, the cap is super tight, I had no qualms about tossing it in my handbag (I don't like to assume gender so not sure if this is a concern for you). I am still breaking in the atty so, it's not super flavorful yet but it has improved with use. We'll see if this continues to improve and how different juices vape. I can't see myself with a sword hilt sized device (just personal preference), this gives me a good amount of oompf for the size - the lea is obviously bigger than a KR808 but nice in the hand. The lea is also quieter than the KR808. That said, I tried one of my favourite (and finicky) secondary vendor juices last night in the lea and can say juices that don't like to get hot could get a bit scorched <-which may just be the nature of a bigger battery than I am used to. Can't attest to how long the battery lasts since I only used it last night. I'm always in front of a power source so, it's less of a concern for me. Anyhew, I am thrilled with my purchase, but then I'm not comparing to the much vaunted eGo. I may have to check out this Leo everyone keeps going on about!
Hope that was helpful, if a bit of a ramble.
Update: Flavour is really coming out now with thick, creamy vapor. It really is a very mouthy vape, like you could almost chew it. PT function is brilliant.
