I have been vaping,for almost 2 years,but not real experienced,nor Tech minded. I quit using the Blu,but would not recommend them. I was a 2&1/2 pck a day smoker,am 50 yrs old. What works for me,is the Ego 1000-1100,this will give you 9+ hours between charges and I vape all day,retired,so no stopping. I use the Texas Tuff tank,from Vape Dudes,or you can get them from the maker @ Valley View Vapes,same price. I use the Boge 35mm carto,have used both Low and standard resistance and I prefer the Standard. Not really experienced with juice companies,have used Johnson creek and mountian oak and both are ok,but price,service AND FLAVOR,you can not beat Vape Dudes. They are constantly out of their hardware,as they have the best prices,so I use Valley View,for my back up. I want to keep it simple and for me the Ego-T Batt and the Texas Tuff tank works,great vapor and you taste the Flavors. I have used the CE-4s,but found too many DOA's and problems. Hope this helped
