I'm jut starting the 2nd month of vaping. I began with a 510 knock off and it was great because it felt more like a cigarette, but after a week and a half I bought the ego and haven't touched my 510. the ego doesn't look like a cigarette but I like that. I am truely More satisfied with it. The battery of course lasts longer which is great. You don't have to carry a charger with you. The ego and the 510 are both customizable and there are a ton of options to explore. If you need it to feel like a cigarette to start than go with the 510, but if you deciding vaping is for you.. You'll probably end up buying an ego. No biggie though, all the 510 parts work with it.
