as the header say, i was expecting little bit more from the ego mega atty and cart.(i might get the riva from L/B as well, for back up) it makes a gurgling sound and the vape is not as good as what comes with stock. i find myself sucking til im almost light headed and while i still take this over an analog,i cant see using the mega stuff for long. i havent tried cartomizers for it, many of you are suggesting boge 510 lr (2.0) cartos...does anyone know who has them in stock, and would you recommend cartos over carts? no...im not going to try drip since i drive alot while smoking. i am still intrigued by the go-go and maybe even the leo, altho ive read some negative reviews on it as of late. any input is appriciated.
