If your thinking about getting the blu, read this first. As you can tell, I'm not a real long time member here. Like most of you, found this site and did a lot of research, a lot. I thought I had narrowed it down to what I liked and the blu advertisement got me. Thought, what the hell, I'm only out 60 bucks and I'll try it. From day one, had problems. Read and did some of the modifications and helped some, but still, PITA to have to constantly put the liquid in. You also had to be careful how you carry the pack, unless your carts are covered, if the PCC is not upright, then the liquid will leak out and a lot of work to clean. Then the PCC died, two batteries and one atomizer. Did get them replaced from blu, but had to fill out the sheet, remail it. Went ahead and got some extra parts. So, I'm in this for roughly right under 100 bucks. As time went on, other things began to fail, but still kept the faith. Started looking into using carto's, like the 306. Started looking at Volcano parts and stuff, then got to realize, I'm about to waste a lot of cash on something I'm not exactly sure will hold up. Along with the constant battery charging and short life, screw it. Researched that size does matter for my needs....longer battery life and more liquid, so I went with the Ego. A lot of you will say, it's too big. No it's not, it fits in the palm of your hand. Unless you just absolutely have to have a "cig" hanging from your mouth, it doesn't matter. I got the ego, with two batteries and two atomizers for about 65 shipped to the house. Comes with 5 carts that you can refill because the liquid that comes with it really sucks. All my problems went away....battery life is about a whole day, refilling has come down to once maybe twice a day. It's bigger and you can easily put it in your coat pocket or shirt pocket. I'm not a troll or a salesman of any type, just your average government office drone. If your new to ecigs, this is what you'll want to get. I wish somebody would have sat me down and explained it all to me. If I can help a brethren out and save some money and make them totally happy, that's what these forums are all about. Trust me, this advice will save you some serious coin. The ego needs no mods and the throat hit and vapor is out of this world. Also, get away from automatic batteries, they just don't work that well, go manual, as I did with the ego.
