I started vaping in 2010. I am currently still using Boge LR cartos with Ego. I leave off the cap and fill with juice frequently. I recently bought some Halo Cafe Mocha and love it, but in doesn't take long before the taste diminishes (a few hours or a day, at most). I thought maybe it's gunky up in the filler - I'm not sure - I'm no expert. I just wanted to find something that works with this I tried the Protank 2 and hate the cool airy vape. I need a hotter, more flavorful vape. I don't care about the "amount of vape" as far as what actually is seen (actually, the less vapor that can be seen, the more likely I'll be able to continue using it at work). I vape with quick short draws and vape a lot. I hate the new 10 second cut off on the newer Egos I've bought, as well, cause I used to be able to use the smaller, quicker vapes to get it nice and hot and flavorful. I'll take any suggestions!!! Thanks.
